If you're running a malicious user process with write (or read) access to your files, you are arguably already compromised.

The freaking point is that basically anything worth running will have that amount of access, even Flatpaks. And you don't freaking know what's malicious before hand.

		I think that depends on your point of view. I wouldn't run a program on my computer unless I were sure that it's not malicious. And if you mean that some program I already trust could be exploited, that's true even for the Linux kernel or any sandbox / security solution you would come up with. I'm not denying that there's always a risk, but there's nothing good in running arbitrary code that you can't trust.

Exactly the point. You are already fully compromised, sudo adds no security.
