The great thing about this is that it works regardless of how you value the 8+ hours x 5 days a week in person model. Eg, if you’re a founder who can get more value out of that than hybrid or remote, you have oodles of great office space available to you at attractive prices.

Citation needed on that "attractive price" part. In the Bay Area there are acres of empty offices but the lessors are sticking by their asking rents. Vacancy and nominal asking prices are both at all-time highs in Oakland, Calif. The landlords are on a "wait and pray" strategy.

That’s fair, the big changes have been around vacancy not rents. I suspect there’s a lot of incentive activity, or perhaps we’re simply here.

In DC area, the vacancies are worst in the suburban office parks. Which are not where you want your work-in-the-office startup. Suburban walkable centers seem to be doing best, landlords there may be waiting for relocations as office park leases run out.
