let's say agriculture. if you make one tone of tomatoes, one family cannot consume this in a year without becoming red. so should farmers also give it for free?
what about artists? it's not that their work even has a utility function...
It's just the superior FOSS way.
I think plenty of artists would give away their work for free without second thoughts if they didn't have to make it pay their bills.
Similarly most salespeople would gladly work commission-free if it meant more sales.
Now, no, of course not.
Originally though, yes this is how many human economies worked. Surplus was shared in a gift economy.
