Not even that — seeing how cheap Starship launches would be per kg of payload (I've seen a figure of $10), we could as well build a huge orbital station and just manufacture and/or assemble arbitrarily sized stuff in there or even in space. No atmosphere, and especially pesky oxygen, to deal with, no contaminants to keep out, no gravity to fight against. I'd imagine that any scientific and fabrication processes that need a deep vacuum would also greatly benefit from being done on a space station.
