Of course. USA assembly is pretty expensive though, it's a low volume product (so the cost of setting up additional factory won't get distributed across many devices) and I'm not aware of any competition there, so the final price is hardly surprising IMO.

The regular version costs "just" 4 times the PinePhone price, but with Librem 5 you get not only more powerful hardware with more expensive components, but also warranty, continued software development and tech support.
