We may not see on the same level on a lot of things, but I still like you and respect your opinion. I give you a rough time, you give me a rough time, it’s all part of the game.
Here is the biggest issue. And this will always be the biggest issue… What is the one thing Governments are best at? Corruption. There will be no way any regulation will be A.) done with the public’s best interests in mind, B) fair, and C) unbiased.
Say the government begins these outlandish regulatory practices against the doughnut industry. Maybe at first they say all manufacturers that use a certain chemical or compound known to be unhealthy must pay a 75% tax. How soon would companies (lobbyists) push through exceptions, exemptions, etc to have their doughnuts excused from the profit crushing tax? The purpose would be to kill off competition, and the means would be through corrupt legislators. It is a never ending, putrid, festering rabbit hole.
If we need an example of senseless corruption and lobby pressure, we need look no further than our own little cottage industry- vaping. It is being thrashed, beaten, belittled, and strangled unfairly by Big Tobacco and Big Pharma. Misinformation and corruption here is exposed seemingly daily. Money, not public good, talks. It will happen in every facet of government intrusion. So there will never be a fair and just system in place, as long as the government is involved.
So, even if your idea is a good one (and I still don’t think so), it will never be properly (fairly, justly, with public health as priority one) implemented.
That’s not to say that all out of ideas, just that a solution would have to be pretty damned radical, before I was willing to lend it any serious credence. And I’m not about to get all radical on yous.
