That is theoretically possible, but ignores Rule Zero. No GM would allow it.

Ok. But Rule Zero is essentially in this context a stop-gap on what the actual rules allow. The universe as far as we can tell isn't intelligently design and thus doesn't have stop gap feature added in.

Also, I'm not sure what you mean by "randomized rule systems"; these games are highly designed and highly artificial, not random.

The idea here is that even rule systems which are designed to make ascension difficult often seem to still allow it. Still, you are correct that this isn't really at all a sample of randomized rule systems. In that regard, your point is pretty similar to that by sixesandsevens.
