Both have the same number of elements,

That will fall down for infinite sets unless, by decree, you state that
your meaning of "more" makes all infinite sets have the same number of
elements.

There are some rules for comparing sets which are not subset and superset,

 Still nothing about defining set membership, equality and difference in
WMaths though.

Are my rules appearing too reasonable for a believer in equinumerosity of prime numbers and algebraic numbers?

You've been dodging that one for years.  Without sound
definitions of those things WMaths is pretty useless.

Dark elements cannot be defined individually.
