TBF historically systems were designed with such poor UX that it was sometimes quite difficult not to do stupid things. Such as using Windows back in the day without installing software from the internet at large (ie there was no reputable package manager).
But that's a system design issue as opposed to an argument against user freedom.
Is it? I certainly don't do that. We have access to multiple well known and reasonably well designed distribution mechanisms today. Anyone going the curlbash route is doing so of his own accord and with zero excuse if his known bad choices bites him in the ass.
(For the record I have nothing but disdain for those that choose to go this route. Looking at you rustup home page. In contrast LLVM has the decency to provide an apt repository for nightly images.)
Only that nothing about this requires big expertise. If you are a user of computers, you should be able to navigate the basics. It's the same like driving a car, you must know the traffic rules and how to behave, but that doesn't mean you have to understand how your engine works in detail.
If you want to drive a car you go through driving school and have to pass the tests to get a drivers license. Theres no drivers license for the internet and not really any strict set of rules you have to follow in order to get online - most people pick up a sense for rules online by osmosis, usually about how to not get scammed or get malware - sometimes they have to learn by first hand experience. If we go by your comparison this would be like learning to drive by crashing a couple cars. I definitely believe anyone whos even a little tech savvy underestimates how complicated or confusing technology can be for the average person.
