Alcohol is legal in all 50 states, and people drink it as they please in general. Some states do allow passengers to drink in cars, and some even allow a driver to drink if they are below the DUI limit.
So you have a limited case for your point on that one, that some Americans can’t drink alcohol as freely as others wherever they want to. I can concede that European countries have more freedom to drink alcohol than Americans have. We have a similar situation with cannabis laws, where some Americans have more freedom than others.
I have to say, is that all you’ve got? Some countries have more freedom to get drunk and high. That hasn’t been much of an obstacle for the people I know that get drunk and high all the time though.
