Excuse me, what do you mean by 'paradoxes'? I recall no
discussion of such.

That makes NO sense. If you say all 'universes' exist, that's the
same as saying one big universe exists. And if two copies of the same
computation give you twice the measure when they are in different
'subuniverses', there's no reason that shouldn't be true in general.
