And this is a problem how? Read this sentance:

Isn't the main reason for castling, the fact that they prevent a few flying, teleporting SCs to lay waste to an entire empire?

Quite. Castling is both essential if you want to prevent said empire-trashing, and over-effective leading, as it does, to boring end-games in which 2 castled nations beat their heads together getting nowhere.

The other aspect of the problem is that strategic depth is lost if building everywhere is a no-brainer.

Solving the problem means finding a way to make empires defensible without castling.
