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.
Those old fabs are still able to be useful at all because most applications don't need cutting edge chips. Chips have been Good Enough for decades. And again, if the goal actually is manufacturing independence, buying local chips that are a bit more expensive is totally worth it.
