Just 'donating to creators' works in cultures where asking for donations and giving donations is alright. There are cultures (most developing nations in Asia) where openly asking for donations is frowned upon, and donating to non-charitable organizations isn't considered normal either because most people don't have the disposable income to just give away.

Buying things for daily needs, and advertising for them is still normal.

Unless you're willing to turn Youtube into a 'Developed western countries only thing'(which already exists - it's called Youtube premium), advertising is a better option.
