You don't think $8.9B would do it?
TSMC's estimated costs in 2020, were $12 billion for their first fab. In 2025, their updated estimates were $65 billion for the first three fabs and $165 billion for when they get to six such facilities. So, $8.9B is a lot of money, but isn't anywhere close to 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".
