Canada

My mom 'retired' with 'much much less than "millions"'. She stopped working at 75.

She lives in a small $2/sqft/mo rental with dodgy power, asbestos in the walls, windows stuck shut, people staggering past the fuse box all night, miner bees in the walls, and shit Internet. It's a coastal town with no access by roads - just ferries - and minimal services. It's a half-day to get there, really, or an hour's flight.

you may need to experience your version of 'doable' before you commit to it.

Being a homeowner gets you there in a lot of places, it doesn’t matter because you still need a home so you can’t live off it

Need millions to retire even in Canada.

I mean that too, but also cost of living, rent if you don't own a home, etc add up over the two or so decades you'd expect to live after retirement. And if you do own a home, congrats you're a millionaire.

Sure, but we don’t “need” anything above our basic survival cost, let’s go live on the Savannah and hunt our food again.

For me the problem are those who hoard wealth, who don’t earn a salary but sit and live off their massive pile of accumulated wealth. We need a wealth tax now.
