Weatherspoons encourages binge drinking, daytime alcoholism, etc. Those aren't the pubs that are closing.

I was in a pub near St Pauls earlier today, one built by Christopher Wren with some friends I hadn't seen for a long time ahead of a mattine performance. The four of us sat round the fire, one had a pint of draft peer, another half a pint, another a mulled wine, and another a coffee. Certainly not expensive -- less than the cost of a coffee from starbucks, certainly not a pit of misery, and I didn't get the impression anyone near us was miserable.

Meanwhile just down the road are chain stores selling heavily processed junk food causing far more damage, but I'm sure you consider them healthier because of your puritanical beliefs.
