Assets will always keep up with inflation, probably exceed it, which your model isn't accounting for.

The poor own cash. The middle class own a house and a 401k, but usually don't amass enough to retire early due to lifestyle creep. The wealthy own large amounts productive assets with a limited supply like equities and real estate. Now Bitcoin factors into the mix. But if you want to retire and be insulated from inflation you need to own what the wealthy own.

Sure. But I was talking about spending money. You can't spend your house or your car. And your car will most certainly depreciate. Assets are also not immune to restructuring and downturns. ie they carry risk if you're holding. Just food for thought I guess.
