No shit. And you're suggesting lots of financial pain for people who can't afford it in the name of your ideology.
The OP also didn’t suggest or implement the change, but only commented that they liked the results with regard to car ownership and use
How about we eminent-domain wherever you live to build a train line? Oh that wouldn't be a problem for you? Congrats on being in the top 10% at least.
Nah, its not a problem because I'm fine contributing to society. If you need everything to stay exactly as it is or you think your life will fall apart, then I have no sympathy for you.
I do believe if we need to do something like eminent domain then people should be compensated and cases like Kelo v. City of New London were pretty disgusting, but I am not going to pretend that we cant change because people were inconvenienced
Do I support the ability of people to travel to their job, shopping centers, or any destination they like?
Absolutely!
Do I think a privately owned vehicle, which spends 90%+ of its active life being parked in spaces that could be utilized much better otherwise, is the best way to achieve those abilities?
Nope. Sorry.
Cool. Because if you were suggesting that in the real world then, at least in America, you're suggesting a complete overhaul of almost all transportation infrastructure and saying that no average person will have to spend an extra dollar to pay for it somehow. Is Mexico paying for it or something?

Even in many parts of America (which are not that different from many parts of, say, France, which I'm very familiar with, thankyouverymuch), private car ownership is not an absolute requirement.
Can people there get around with Public Transport<tm>? Nope. Do they require their Own Private Sardine Can At All Times<tm>? No, not necessarily either.
And I'm firmly in the "No Sardine Cans Ever!" camp, and I have solutions. If you're somewhere else, that's fine with me, but you're not so convincing as you might feel...
I've been to France as well, outside of major cities. Perhaps not as well traveled as you, but I remember seeing plenty of private cars in driveways and on roads as we passed by various dwellings. I doubt they'd take kindly to your suggestion either. Weren't there riots over the price of gasoline not that long ago?
Whatever, be a flat-earther of transportation policy if you wish. You clearly aren't serious.
