Why would you trust an oligarchy of politicians (the State) to decide which goods are useful “for a community” and which don’t?
Because we voted for them. We didn't vote for the board of directors of private companies. There's plenty of waste and corruption in private enterprise. It's not voluntary if they lie cheat and steal just like bad politicians.
Yeah that's huge, why pay full price for a buggy game when i can buy the patched/optimized version of the game for half price a year later??
