Thank you, Russell, for your wise comment. Indeed, IMO Planck's 'units' are
a quantized semantics of a philosophical identification about our physical
system.
Our present observation does not go further than the (now unobservable)
Planck measures. So the Planck unit is - yes - trivially "1" (for us), but I
cannot take it for granted in a wider view with a possible further
"structural" resolution of it.
On your second par: we are still hooked into our anthropocentric system of
quantities. We may think so slowly, because our mass (inertia, whatever) is
so "big". Relative to what? the universe thinks (changes) much slower.
