| > a practical erasure of any line at all Not really the Texas power grid is hardly the only example. Banning products like say Fireworks is a much broader exception. If there’s no marker to regulate then the feds can’t get involved. This applies to more than just total bans, it’s also why California can have such influence on automobiles and Texas influences textbooks etc. You may feel there’s not enough things that fall into the exclusion, but that’s not the same thing as the exclusion not existing. > address the problems incident to interstate commerce Trademark infringement on trademarks held by an out of state entity breaks the principle you’re talking about without any sale directly crossing state lines.

This isn't because the existing commerce clause jurisprudence excludes the federal government from regulating these things, it's because the federal legislature passed legislation carving out an exception for California to do that:

Trademarks are already regional. If there is a Joe's Diner in California and another one run by a completely different Joe in Massachusetts, there isn't a problem any more than it would be if there was an independent Joe's Diner in Canada or England. Whereas if there is a Joe's Diner chain headquartered in California which is operating franchises in Massachusetts and they therefore want a federal rather than state-level trademark on the name, that's interstate commerce. Making interstate operations a prerequisite for a federal trademark would not be a real problem.

That's not what happened in Wickard. The state wasn't subsidizing anything, the federal government was prohibiting farmers from growing wheat. One of the farmers grew wheat for his own use, in the same state, and was fined for it.
The Court's theory was that this affected interstate commerce, because if he didn't grow it then he might have bought it. Which is a problem if you're trying to do national-level central planning of wheat production, but that's not what the commerce clause is supposed to be for. Everything "affects" interstate commerce. The purpose of the grant is supposed to be to deal with the issues that arise specifically as a result of commercial interactions between people in different states.
