I wouldn't call myself an expert on this topic, but I think you're severely missing the point: virtually any case involving use of the internet can be federalized under the interstate commerce doctrine.

Everything can be federwlized under the interstate commerce doctrine. There was a case where a farmer grew his own plants (wheat, I think) to feed himself and his animals, in contravention of federal quotas. It was ruled the federal government has authority because growing wheat affects the wheat market, even if the wheat is never sold and never leaves the state.
