the question is if single country can carry all these industries at loss for prolonged period of time.

Another approach is to rely on international supply chain and speed of innovation, we can't produce steel domestically profitably today, fine, we may buy it from diversified international supplier network, and rebuild it fast tomorrow if needed using new tech, and focus on many other high margin verticals, instead of putting many billions of resources into infra which could be obsolete tomorrow.

This is fine as long as the supply chain is, in fact, diversified.

sure, looks like more analysis is needed to check which verticals are diversified and which are not, instead of throwing blanket list of everything.
