I'll see your wish for a yawn rating, and raise you one deep longing for a massive eyeroll.
I'm noting a pattern between folks who like to substitute emojis for arguments.
I also only just now noticed these edits...
Edit: cornering markets and hiking the price is a common practice that I shouldn't have to explain.
Edit 2: But I will... in the words of Vito Corleone: when I thought I was done, they pull me back in
Here is how you can corner a market: say there are 5 apple vendors in your neighborhood, each of them employs 3 people and apples cost $1. You have a lot of money and you want to make some more so you want to corner this market. What you do is you sell apples at a loss (below the cost) say at 25 cents, so everyone buys apples from you and stop going to the other vendors. You will be losing money but it is temporary and it is an investment. You put up with these prices until all the other 5 vendors are out, they closed shop. They can't fight you because they don't have enough money to put into it and sell at a loss. Once you are the only apple vendor in the neighbourhood you start selling apples for $2. How does this fare? Well, you are making twice as much as you would do otherwise, but you crashed 5 apple stores, left 5 families without income, left 15 people out of a job and the entire neighborhood has to pay twice as much per apple or go far away to buy them cheaper. Congratulations, you fucked over society to make individual profit.
First off, you still never bothered to argue the ethical nature of taxation, to which your quip about a yawn was about, but hey, lets actually get into your argument.
Here is the problem. The irony of your accusations earlier about what libertarians or ancaps think or do, ones you haven't acknowledged were either ignorant or lies when called on mind you, was that you accused them of taking things in a vacuum, when in reality, this is what you now are engaging in in an attempt to make a point. You're tightly controlling so many variables as to produce what you think is a winning argument, but really it just shows a poor grasp of economics. Because, lets actually break down what is wrong with this theoretical scenario.
First off, how did you first get this 'lot of money?' that allows you to somehow come into a small market and completely undercut them, and survive those losses? By its nature, in a purely free market, the only way to amass such wealth would be to do so by providing actual value to customers. Which, incidentally, you then do again even if you are undercutting costs, because suddenly the consumer is getting apples much cheaper. I'll assume, then, that apples have a cost of 50 cents to 'produce,' that is, to grow and harvest and bring to market, for the sake of this because they have to have some cost, and also some profit, unless you're trying to say that these vendors were selling them at cost, which wouldn't really make a lot of sense. So, lets take that, and then say that this person with a lot of money enters into the market, and sets up a rival company. Well, first off, they're going to have to invest in the infrastructure to enter the market, which is to say they need to invest in orchards and facilities, and thus hire individuals to both build these facilities and maintain them, and pick the fruit. They're going to need to hire people to sell the fruit. This is tacked on to their costs of also selling their product below production cost, bringing several questions up as a result, but most notably why, if they are so rich as to be able to absorb all these costs, are they engaged in such a small market in this way?
Furthermore, this implies that all five of the other vendors cannot weather this long enough to survive till you go out of business, because you're basically playing chicken with them. Further, even lets assume you manage to make it, and drive all five out of business, then jack up the price. You're not actually making a profit yet and "society" (more accurately, the local consumers of apples) has not yet been screwed over, because they had been receiving apples for BELOW cost for a long period, and will continue to do so until such a time as you recoup losses for having sold BELOW market value. In the process, you say you've driven these other companies out of work, but this implies that any company that is smarter than another and drives a rival out of business is somehow immoral because it denies the other company income. It also implies a zero sum that they cannot go into some other business. Further, these five companies now have their assets on the market too. What is to stop another company from coming in, buying out these assets at a low cost, and then selling apples for $1, which you no longer can do because you already undercut and are running in the red? Your scenario posits this end, but that isn't the end at all, it's just all one continuum of market activity.
And, of course, I mentioned earlier already the fact that to even enter the market, and sustain yourself in it, you must create jobs in the process, in the form of the employees and contractors you hire to build and maintain your facilities and sales.
Congratulations, you made it abundantly clear you have no idea how economies operate.
I want to note something: there was a post I rather like earlier in this thread, in part, talking about while they agree taxation is wrong, they're more interested in finding ways to gradually reduce it. I agree, generally, with the post, but would point out that the discussion never got that far, because the very moment I brought up core principles, I was instead subjected to strawman arguments (where arguments were even provided,) long before we could progress to practical discussion of how to go about implementing ideals.
