Privacy is not a binary state, but rather something of a spectrum ( and partially a reason as to why Google and others try different avenues for siphoning data ). Every little bit helps a little bit depending on your tolerance and skill level. I genuinely do not expect my mom to run FF with appropriate plugins from a scrubbed VM each time she wants to check something. But I can give her some sane defaults instead.

I agree with your general point, but ignoring an issue just because there is no 100% solution is not reasonable either.

But that isn't what I'm proposing. I'm saying that when you buy a vehicle, and the driver's-side door, by design, unchangeably, cannot be locked, maybe you shouldn't buy that model of car, rather than try to hack privacy into the vehicle by adding an aftermarket passenger-side door with laser tripwires and barbed wire.
