> getting to the equivalent to what TSMC has in Taiwan
That wasn't the question. The question, at least for me, is can you build non-zero chip production, enough to start building out a sustainable business. Obviously you're not going to compete with TSMC on day one, but there's a wide spectrum between that and "garage".
How would you build a sustainable business based on old processes though? The only reason fabs exist that use old processes is because they were once new processes, and once they've been built you may as well keep them running for a while. Building a new 50 nm fab would never be viable.
