Who’s in favour of trouble-free drinking?

I disagree with those people that want to see the ‘happy hour’ in pubs being scrapped.

Unless you live in John O’Groats or the Orkneys, drinking in pubs has become a rather expensive exercise, therefore the ‘happy hour’ is a rare opportunity to enjoy a drink in a pub at reasonable prices. At the same time I have a lot of time (and sympathy) for those people who are sick and tired of drunken morons spoiling it for everyone on almost any given night.
Maybe I’m old fashioned in suggesting this.... but why don’t we just apply the existing law, whereby pubs that keep serving drinks to visibly inebriated punters are either heavily fined or (even better) or have their licence revoked?
