Though I would gladly see Wickard v Filburn overturned. Commercial regulations already vary by state, and the US would still be more cohesive than the EU is today, but the amount of water that flows through my showerhead doesn’t have to be a concern of the federal government. In fact, we don’t even need Wickard v Filburn to be a more cohesive federation than Canada, which doesn’t even have free trade between provinces.
States can still do civil rights etc.
Be careful not to be anachronistic. When the US was a young country, before telegraphs and railways were widespread, most people's primary interface with the government was perhaps their municipality or at the highest level perhaps their county.

I am not so sure. Different people in different parts of the country have different preferences. Much easier to satisfy them, if you don't centralise too much.

Much better to elect 3,143 kings, one for every county. If you don't like the one your neighbours (and you) voted for, just move to the next town over.
