Reliance on other nations for critical resources is a separate concern from technological mechanisms for acquiring those resources, even if the later may help solve the former.

I think reliance on highly-concentrated markets (globally/nationally) for any critical resource is the bigger issue.

You're missing the point a bit.

Replace energy with food, water, medicine, microchips, or any other commodities necessary for modern life and the point still stands.

I think I understood the point. The counterpoint I was trying to express, in response, is that this is a consequence of allowing high-concentration of market power in many of those commodities, nationally and globally, without any checks and balances.

Yes, but this is entirely at odds with globalization. A primary reason we outsource production to developing countries is to exploit their lack of regulation (including environmental regulation). If the UK transitions to green energy, they’re not subject to Putin, but they’re still subject to Xi and they are still contributing substantially to emissions. Moreover, transitioning to green energy will probably create reliance on rare earth metals and other minerals that will likely be controlled by despots.
