I don't want to assume your case or the opposite. What I want is for
people who speculate on these things to acknowledge the uncertainties
up front, rather than at the end of a long conversation. I see way
too many baldface claims of the form "with nanotech, X will happen".

I'm not speculating. Production, including labor to run it, only
takes about 15% of US GDP (I think). Standard econ statistic.

I think you are mixing timescales. Eventually, good public domain
designs may become widespread. But by then lots of other stuff may
change too, including an upload population explosion. And the private
designs may be far superior, and so worth paying a premium for.

You are talking about pretty advanced designs, and so not about early
nanotech. You need intelligent machines to make your life that easy.

Of course there are feedback mechanisms. But that doesn't imply fast
change, only change at some speed. Imagining, designing, testing,
tuning, marketing, etc. of designs all takes time and intelligence.
And make no mistake - nanotech design is HARD. These are very complex
machines that are imagined.
