Yeah that's why I threw in "maybe sooner". $25m is a bit arbitrary but is also somewhere around the point at which I'd have to start trying to waste money before I'd risk touching principal. That's "never think about money again, even a little" territory, for me (but then I don't want a yacht or any of that), so at the top end of the range in which I could see myself deciding never to work again.
Also, $7.5m is still low enough to be threatened by healthcare costs and end-of-life care and such (x2 for a couple, plus if a kid gets very sick before they're out, or even after but you don't want them to be ruined by it, et c). Not enough to wipe it out, probably, but enough to diminish it substantially if you get a bad roll of the dice. I wouldn't even need that much to stop having any motivation to try to make more, if I lived somewhere with decent universal healthcare where having your savings eaten by the healthcare/hospice-care industry is practically unheard of.
