It’s very literally interstate commerce when presented in that fashion.
Article 1, Section 8, Clause 3 of the US Constitution specifically empowers Congress “to regulate commerce with foreign nations, among states, and with the Indian tribes” (emphasis mine).
If that doesn’t satisfy someone’s definition of “Constitutional Originalism”, then I don’t know what will.
Suffice to say: all of these regressive laws around trying to prosecute abortion-related travel and transport of goods that are coming from the legislatures of those states are absolutely unenforceable and categorically bullshit.
