Maybe just the ones that could be used to send all your money to scammers from your bank account or crypto wallet?
Computers are cheap these days. You can buy a Raspberry Pi to hack on and use something else for your money. If you like hacking on smart phones, carrying more than one phone is an option. You don’t need root access on every device you own.
I'd want a separate, secure smartphone only for auth/banking... but Google makes this impossible by preinstalling their unremovable spyware. And if you dare to remove it, then poof - your device is no longer considered secure. Google knows what they're doing.
We should implement mechanisms that make it hard and obvious to do unsafe things and easy to do safe things, in all kinds of computers; even as an expert user, I don’t want to have to think about my text editor’s color scheme being able to access my bank. Yes, this necessarily involves a barrier to installing apps with certain privileges, and it should be high enough in software targeted at non-expert users to provide them with protection against scams. No, we obviously shouldn’t make it illegal for a user to do what they want, and nobody has even come close to proposing that here. That’s a straw man.
