If you try to take too many eggs out of 1 basket, the person carrying that basket is likely to try and run away. So it’s easier and less disruptive to take a few eggs out of lots of different baskets.
Taxing accumulated capital without exceptions is also guaranteed to screw people over. The man in the OP is a good example: he’s a modest man who many years ago bought a modest house for a modest sum of money. Due to circumstances, that house has now increased in value, making him a wealthy man on paper. But he’s deriving no income from that wealth, since he can’t rent it out because he lives in it himself. So now he’s a modest man, who is rich on paper, who is expected to pay high taxes on his paper wealth, turning him into a poor man who is barely scraping by.
And that man clearly does not live in such a state, nor did I (or anyone else I think) claim that his circumstances apply to the entire usa. You’re wrong in assuming that other people are not aware that different places have varying laws and tax systems.
Your whataboutism defence of regressive tax systems is also very strange to me. That other places have unfair practices in place, is no excuse to put up with an unfair system in any one place. Call them all out on their brokeness, but if you do call them out, you’ll have to be more specific in your example(s), state things that are actually verifiable instead of some vague whataboutism.
Ps, while I did not think your whataboutism defence was relevant, this “Little wonder that property ownership rates are generally so far below american ownership rates.” was easy to verify and it turned out to be false. Home ownership rates are on average slightly higher in Europe than in the usa, here’s statistics: https://www.statista.com/statistics/246355/home-ownership-rate-in-europe/ https://fred.stlouisfed.org/series/RHORUSQ156N
