It's very true, though. There's something to be said about technology you can build without a huge capital investment. With maybe $50k worth of tools and materials you could probably build a vehicle from ~1980. You can't manufacture them at scale, and if you factor in your time it won't pay out, but you could in principle get it done with accurate drawings.

Proprietary software, though, is a huge moat. And the complexity that comes with it. There's no reason we shouldn't be able to build more modern cars as one-offs, except that the systems are so locked down
