What is stopping someone like Twitch to have their own "Patreon" service that allows donations?

They do, it's not as robust Patreon's is but it does allow for tiered subscriptions ie 5$ per month which is standard, and say tier 2 being 10$ and tier 3 being 25$. The perks are getting badges and emotes which people seem to accept well.
