If there's work that needs doing, that work should pay a living wage. If it doesn't, yes, it shouldn't exist. Raise prices until it can support those workers, and if people won't buy it at that price, get rid of it. Otherwise, the argument you're making is that someone needs to do this work, but that person should be destitute.
If someone wants to do something on the side as a hobby, that's fine, and that's not what we're talking about here, obviously.
