Removing network connectivity from basically any new car is trivial, often as simple as pulling an easily accessible fuse.
I'm guessing that you haven't actually done this on "basically any new car".
If you had tried, you would know that there is no fuse dedicated to "network connectivity". It is typically tied in with other, often essential functions like the engine control computer --- specifically in order to thwart a simple disconnect.
What I have seen done is to tear into the right roof pillar and cut the wires going to the antenna on the roof. But this is usually not without consequences as well such as a perpetual error code display and/or the radio, navigation or entertainment functions stop working.
I've done this on a W222, a W223, a continental GT and an Urus. On each of those cars it was as easy as disconnecting the antenna, on none of them did I have to tear into the roof pillars.
I've never seen an antenna that was difficult to disconnect, on the super simple end you have something like the W222 where you can literally just pop out the antenna cover on the roof and just remove the antenna module inside.

Well sure, I do have cars without GPS because I was lazy. Carplay still works fine, so can't really bother to do anything about it.

That largely depends on the specific vehicle. I’m surprised that there wer no negative effects in pulling the telematics fuse on a W223, less surprised on a W222.
