And yes, they have every right to buy it and do whatever to it. But that’s not the point here...it’s about people’s intents and how one of two sides is greatly affecting the other, and the other one is not:
Side 1. Someone intending to scalp/profit with nothing to lose.
Side 2. Someone who really wants the X and waited, and/or saved up for it, but the scalper gets his spot in line.
Which side are you on?
Another simple analogy to this:
If you are trick or treating and you find out all candies have been taken from all the houses, then a kid comes up to you and offers you those candies for a price, what would you do? Of course there will always be other kids who will buy them, will you be one of them?
Think about it: The fun of trick or treating ruined by a kid whose main goal is to profit from others.
