The substantial issue is not "unconstitutional" or "revenue", but instead "corporate protectionism". The elephant in the room.
There are certainly concerns about home distillation. The question is whether We address those concerns uniformly or whether protections of "tax revenue" is really protection for corporate interests.
We live in a time of toxic corporatism. Not all corporations are toxic, but those who prioritize their interest over the common good are indeed toxic. Everyone has the right to use nicotine and smoke cigarettes. You can buy them - if old enough - anywhere. But the use of cigarettes is toxic. As are vapes. But some corporations believe that their wealth is worth all the early deaths and health costs that a lifetime of smoking brings.
It is the behavior of these corporations that is the issue here. Those who take the Friedman Doctrine to toxic extreme. The courts have promoted these greedoconomy by enacting United vs FEC and other anti-democratic policies. In contravention of their duty.
Corporate interest have become so powerful that we have become a corpocracy rather than a democracy.
Jeff Bezos has "Democracy dies in the dark" as the motto of the Washington Post. Democracy dies with the Friedman Doctrine and United vs FEC. Thanks Jeff and to all of the other corporate overlords.
