but I'll guess that maybe he thinks that the list of powers in Article I section 8 has an implicit "... and these are all the powers that the Congress shall have" and he's upset at their having more; or maybe he thinks the Tenth Amendment ("The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.") isn't being taken seriously.

Yes, basically there are some people like myself and Murray who think the US Constitution delegated enumerated powers to the Federal Government, and that this constitutional order was overturned in a judicial coup over a number of decisions that expanded the Federal Government's presumed authorized powers to most anything under the sun that isn't expressly forbidden, and sometimes even then.

Constitutional conservatives have been complaining about SCOTUS just making shit up at least as long as I've been alive, but I don't recall anyone prior to Murray assembling events of this slow motion coup in a single book.
