I don't think that's true. Sure, at some point you stop producing economic value, but we don't mind people retiring at 65. What's so magical about that age?
If you contribute enough productive value (as determined by the free market, paid in some asset), why does it matter when you retire? I'm sure there is some endgame where we stop funding our consumption economy to the same degree we are now, but is that a reason to work until you can't anymore?
You can only kick up your feet if you've done enough "economic output" in the previous years, it's not a free lunch. This is coupled with the fact that most retired persons do invest and contribute capital. It's not at the same level as Mark Cuban, but does it really matter if you only invest a million vs 700 million+?
Nothing magical, because when people age they become less healthy and able to work/contribute - it is only ethical to offer them the last ~10-20 years of their lives as reward for their hard work. The average age of death in the US is 78
And who pays for the benefits the elderly (or as a matter of fact, the whole society) enjoys? Amenities, welfare, health insurance, etc. - taxpayers, exactly the demographic (before 65 - healthy & able-bodied) FIRE is encouraging to stop working, thus avoid paying income taxes.
