Edit: You think people should be banned from doing stuff if it makes it less pleasent for you? Have you ever actually thought through how free anyone would be if this were applied reciprically? If anything that impinged on the pleasure of another were banned we would, literarly be living in a totalitarian state.
Well you've made me think about it.
I try not to negatively impact other peoples lives as much as possible. I avoid eating, drinking, farting etc. in public because I don't want to offend anyone.
I find the consumption of alcohol on trains discourteous to fellow travellers, not harmful.
There are many hundreds of thousands of people who don't drink for various reasons, some of whom will be offended by the consumption of booze on tubes.
I think that anyone who can't hang on for a few minutes until they are out of a tightly enclosed public space before cracking open a can should be receiving help.
I think the British drinking culture is shit, and that the loss/gain ratio of stopping boozing on tubes will be generally advantageous to the majority of tube users (lost=nothing, gained=a more pleasant journey for all but the drinkers).
