The fact that alcohol is sold in stores en masse, but it's somehow so bad that it kills cells? If it is so bad, why isn't it banned in every country in the world?
Beer is even considered food in some countries. I don't see any evidence for his theories mentioned in the video.
Alcohol as a “cultural lubricant” has been with us for as long as humans have had oral histories passed down. The alcoholic beverage lobbies around the world are politically powerful and have very entrenched interests within countries.
The United States attempted to ban it during Prohibition. That social experiment lasted 13 years before it was repealed. If you’d like to understand what makes your proposal for a unilateral ban challenging in practice, understanding why Prohibition ultimately reverted to the previous status quo is a good starting point.
One reason why Prohibition didn't work (and why alcohol has been culturally significant for so long) is that alcoholic beverages are ridiculously easy to make. If you have fruit or grain, a container, and some time...
Attempting to regulate alcohol, as you note, is a fool’s errand.
Regulation isn’t the answer. It will take centuries of messaging and a shift in consumption patterns before it’s not profitable to commercially produce. Possibly.
