It's not entirely cut and dry, your money in a stock market index fund tends to keep pace with property appreciation when accounting for maintenance costs and property taxes. But you would be insulated from skyrocketing rents.
More financial freedom, but only if you're already wealthy. Plenty of people live in cars and doubt see it as something luxurious. This is definitely some "cosplay poor" type shit.
He lays out the financial reasons why you'd save money without a car, but it does assume you can afford to rent or get a loan for a house/apartment in a city in the first place. Are you suggesting that is an unreasonable demographic to target with this advice? Because that sort've implies that any cost-saving measure advice should only be for those in the most dire financial straights, if I'm understanding you correctly.
Homelessness is a horrible and cruel epidemic, but if anything, the advice in the video could be seen as helpful to avoid becoming homeless, or at least to ease the overall financial burden on people who are already on the edge, not for the wealthy, but that's just my take.
Plenty of poor people in cities also live without cars ¯\_(ツ)_/¯ Taking the bus is going to beat the cost of a car pretty much every time, even accounting for situations where a cab is necessary. Only works if your work isn’t reliant on a vehicle, your city has okay transit, blah blah we all know this comment wasn’t supposed to encompass all possibilities.
I never hear my neighbors in my apartment. I'm also living close enough to bike or take transit everywhere I want to go, and spending less overall on housing thanks to being part of a very well run apartment cooperative. I also get to skip out on the major hassle of having to maintain everything in the building I own myself.
There's even a gym in the building which costs a rounding error per year to be a part of.
