"Plank units are not physical limits on reality itself" is what I should have said. We can obviously have larger or smaller masses.
The plank time is a limit on a measurement process, not the smallest unit of time.

We don't actually know that. They might be. Planck units are what happens when GR meets QM and we just don't know yet what happens there.
But as a heuristic, they probably put pretty good bounds on what we can reasonably expect to be technologically achievable before humans go extinct.
