Interesting way to define consciousness, the thing that goes away when
an a general anesthetic is applied. That can be quantified.

Uncommon, but certainly not unheard of.

Given that microtubules are very widely employed in all cells for all
manner of purposes, blocking microtubules does not imply that quantum
mechanics are or are not involved, as blocking anything that
fundamental is likely to affect very many things.

True, but unhelpful.  It's not enough to observe that if A is blocked,
B stops working, and therefore the mechanism is X.  There are many
mechanisms simultaneously in action.  One must methodically rule out
all but a single X to claim causality.
