I really think Linux should make it harder somehow to uninstall critical parts of your operating system.

Yes. This was one of the things we had to polish way back in the first Linux boom when I was working at Lindows. We got a report from QA that "when I uninstall this random thing called dpkg I can no longer use the app store". After the lead dev managed to collect himself from off the hallway floor (the only literal ROFL I have ever seen), everyone realized that yes, you should be prevented from uninstalling the core software.
