Well unfortunately most government/politicians don't have the knowledge to pass laws on their own, especially in technical industries. Lobbyists are obviously incentivized to have favourable outcomes. But how else do you pass a law without hearing from industry? If you were regulating marijuana but never used marijuana, how much THC are you allowing to be put in edibles? How is the the THC measured? How do we define the quality of THC, if possible? How do we require the declaration of THC content to be presented on packaging? Industry guidance (influence) is necessary, lawmakers can't do this on their own.
