If somebody asks for charity, many people give them charity, because we owe that much to our fellow human beings. If the same person works for thousands of hours, and then says "hey, remember me? I gave you this thing that took thousands of hours to make, and I desperately need money, can I have some?" a large percentage of people will say "fuck you, how dare you try to shake me down for money!"

A slightly more nuanced but equally confounding position is: "I'd give you money, sure, but your license doesn't require it, so go piss up a rope buddy".
