I can see the arguments for the pointlessness of this ban. Any rule is pointless if it cannot or is not enforced, the entitled will do what they like regardless.
It seems we generally have an unhealthy attitude towards alcohol in the UK. I'm not saying other countries are free of drunken behaviour but my perception is the UK population seems to be particularly bad at self control. Back in my school days I was allowed to have a small glass of wine with a family meal and thought nothing of it, it was a normality for me. I wonder if that was a factor behind me never getting into the drinking culture at university, because alcohol was never a forbidden fruit for me so I felt no desire to consume as much as I could get hold of.
It probably should be noted that drunk and disorderly behaviour is not just an issue on trains, it can be a problem on other modes of public transport as well:
Group said they ‘were going for it’ and allegedly snuck alcohol aboard the easyJet flight, passengers said

Rowdy British stag-do guests in wigs hauled off Tenerife ‘flight from hell’ by police
A British stag do party were removed from a “flight from hell” to Tenerife after it was alleged they drunkenly abused air hostesses.
The group, made up of at least ten men some dressed in wigs, loudly shouted on the easyJet flight that they were “going for it”, passengers said.
Those on board the flight claimed the group had smuggled alcohol and board and nearly brought female air stewards to tears after they refused to hand over bottles.
Duncan Young, 56, a passenger on the 4-and-a-half hour flight told
The Independent it was the “flight from hell”.
He said: “The captain was aware of two stag parties on board and welcomed them with a warning to ‘behave themselves’ and respect other passengers.
“But they were already intoxicated. My wife and I were sitting in the front seats by the head steward on board and we could hear that the group of lads had smuggled alcohol on board and were ‘going for it’ in a big way.
“The captain came on again after about an hour and warned the passengers that due to the behaviour of some passengers, the plane may have to be diverted.
“The chaos continued with the group swearing, taking photos of the crew and physically stopping them from taking away their alcohol and then two women stewards came down to the front of the plane. They were close to tears and visibly upset by it all.
“Another meeting happened with all the stewards and the captain to decide what to do and the passports were taken off the passengers. Unfortunately this didn’t calm them down and then homophobia kicked in aimed at the crew.
“We landed and were told not to undo our belts but to remain where we were as the authorities were boarding the plane. They duly did and police hauled at least 10 passengers off the flight."
