People have said this before, and usually got hit with Gnash's "every donation has a different reward, that's enough." locked thread.
Yes, medical at rebel is great, however, it's also an incredible buff to rebels when it's active as you don't have to interact with a town at all. It's meant to be strong but it's also meant to be an "extra cherry on top." IMO, there would have to be setbacks if this was implemented permanently and not require Community Goals / 50k infamy.
While a rework is potentially coming in the future where plates decrease your time rather than bail price, again, the devs need to put some nice things behind a paywall to entice people to donate. The things you listed are quite strong and likely reasons people donate via community goals.
You kinda nitpicked at the better/juicier Community Goals and advocated they be implemented permanently, which, IMO (apart from extra talent points) would render community goals useless (ie: I'd rather spend money on crates or my personal donator level).
