However, if they cannot “contain” a form of commerce within their state, or that form of commerce “commingles” with a federal authority commerce, it is under federal jurisdiction. Today this can mean federal highways, pollution, interstate package delivery, etc.

Federal highways were created for the national defense, so that military vehicles and personnel could be moved quickly. Is that a constitutional violation in your eyes?

Pollution, especially air and water pollution can cross state borders easily. Do you believe that all instances of such pollution must be tried in lawsuits between states by the Supreme Court?

Interstate package delivery. Such packages can contain illegal, dangerous and harmful products, and can be used to facilitate wire fraud. Cargoes of contaminated plants and animals can spread disease throughout the US. If under state jurisdiction, packages can be inspected and taxed by each state it passes through.
