And the government just needs to transmit that information to themselves in the past so that they can know which growers will wind up selling pot and which ones will only use it themselves.
Still preposterous.
Almost as preposterous as this statement...
"The regulation of an intrastate activity may be essential to a comprehensive regulation of interstate commerce even though the intrastate activity does not itself substantially affect interstate commerce."
Complete gobbledygook. It sounds like a line from Alice in Wonderland.
