> Note the Ninth and Tenth Amendments, which explicitly state that the rights listed in the Constitution are not exhaustive, and that all such rights not enumerated in the Constitution are granted to the states and the people.
That’s wrong on the Ninth and Tenth: the Ninth Amendment says that enumerated rights don’t limit other rights of the people that exist (the purpose of this was that the Constitution wasn’t a “blank slate” document, there was law existing before it which established rights, and Ninth Amendment was to make clear that the Constitution did not extinguish them, it doesn’t give anything at all to states; the Tenth Amendment, which does address states, says all powers (not rights) not granted to the federal government by the Constitution are reserved to the states or the people.

No the right to conduct commerce that relies on doing this is not inherent in either the First Amendment nor is such conduct of commerce, insofar as it has an interstate character, protected from federal regulation by the 9th and 10th Amendments, because regulating interstate commerce is an explicit power of Congress.
