Saying that containing 0 things is the same as not being a container
would be pretty broken, though. We shouldn't just deny that 0 is a
valid number.

It is false that, for all X there is a Y such that X is a set
containing Y.
i.e., that says exactly what you'd expect from the the first one:
su'o da selcmi node
there is at least one set which contains nothing.

Since when is a bicycle a set? A bicycle can't go into x1 of selcmi.

I don't see why you can't have it be a selcmi be noda. 0 is as valid
a number as anything else.
