License Alcohol.

You have to get a license to sell insurance.

You have to get a license to practice medicine.

Why not require a license for alcohol?

If you don’t have your license you wouldn’t be able to buy alcohol.
If you don’t have your license you wouldn’t be able to posses alcohol.
If you don’t have your license you wouldn’t be able to sell alcohol.
If you don’t have your license you wouldn’t be able to serve alcohol.

One of the problems now is that nothing keeps a violator from drinking (except for spending time in jail – maybe…) after a violation. This could.

By making any alcohol infraction a suspension of your alcohol license for say 3 months longer than your previous infraction there would be a strong incentive to not break the law or let someone else break the law.

If someone is convicted of an alcohol violation:
A liquor establishment won’t sell them alcohol because the store will lose its license so would the clerk/bartender/waitress.
A “friend” won’t give them alcohol because they would lose their license.
