Sure, given a billion dollar budget, few years to work, and a legal environment that lets them use those stolen secrets. It can't be done cheap, overnight, or where the legal environment doesn't allow it. Really only China, while plenty of places have smart engineers, the rest cannot get the rest together (and if they tried it would kill their economy).

Note that TSMC depends on other companies for various parts. Without those they need even more money and time to duplicate it all. There is nothing they are doing that you can't hire engineers to duplicate. They figured it out, so anyone could. However it isn't easy, we could be talking about hundreds of billions of dollars.
