I agree with you on your take on the Commerce Clause, but I disagree you vis-a-vis the requirement that government involve itself in the Public Commons (as it pertains to Communication).
I suspect I will never change your mind, nor you mine, so let’s see what SCOTUS says about it, and learn to live with that.
Your rationale without constitutional rationale will of course never change my mind and you should reconsider your argument in light of the Constitution AS written and ORIGINALLY intended and understood. The Constitution IS the ONLY basis for legitimate federal activities.
