And have the scope picked up by state and local governments (or even a global one)? Or just let corporations make the rules?

I see the government doing at least two things: setting rules and providing services. Do you want fewer rules or fewer services? Or something else?

In the USA the general scope for federal & state has expanded, with Federal having the most growth since about 16th Amendment. US code & regulations has expanded 1000x , cost per capita is 15000x

I only make the point that there is a broad spectrum of functional scopes for the government, and rather than looking at shifting the scope around, another possibility would be to revert the scope to sustainable levels

Yes, state and local should pick up. The closer to the people a government is, the better it is.

I want the fewest rules that create the most fair economy. And I know very few service better in the hands of government. And that includes bridges:
