This is wrong in so many ways. It will encourage people to basically pretend they're doing some kind of art even if they're not.
If someone is a real artist imo, they will manage. It will be part-time but eventually they will get better and can start making money out of it, and if not then well it can just be their hobby right? Why am I not supposed to be paid for making my own garden look good? Is it art or hobby?
