here’s how crazy SCOTUS is (an actual excerpt from /Quill/):
“Under the Articles of Confederation, State taxes and duties hindered and suppressed interstate commerce; the Framers intended the Commerce Clause as a cure for these structural ills. See generally The Federalist Nos. 7, 11 (A. Hamilton). It is in this light that we have interpreted the negative implication of the Commerce Clause.
…
Accordingly, Congress is now free to decide whether, when, and to what extent the States mayburden interstate mail order concerns with a duty to collect use taxes.”
The ellipsis representing a somewhat thorough retelling of their poor decisions, each building upon the prior.
