The right to privacy is not a 'first world problem', it is a problem.
The specific privacy problem espoused by this post is not just a first world problem, it's an HN problem. I am being disingenuous - this request is pure insanity and I absolutely promise you that this "computer you fully own" will have such a very small market that it doesn't have a chance of breaking even.
Where a right for privacy really matters is not in the part of the world where your google searches are used to pick an etsy ad, but where typing the wrong thing against the wrong person could land you in jail, or at the morgue.
You and the OP have the same problem you want a solution but are not willing to pay the price. And you think that what you want is what most people want, but from what the market tells us they are pretty happy with what is being offered right now.
I don't think you can make statements about me with such a definitive tone without first asking some questions.
