Why not use an adjustable temperature wine fridge?

The wine bottles are laid on their side. Ideally, beer bottles are stored standing up.

Well, just my view, but wine fridges are made to store wine over a long period. Typically only red wines are stored. Beer, on the other hand, is meant to be imbibed relatively soon.

I live in San Diego, pretty much the craft brew capital of the world right now. I have enough beer on hand to last me about two weeks, from IPAs to lagers. They live in their cases in the garage, and I put in my regular fridge an assortment to drink.

Just an aside, but I see many brewers are finally switching to cans.

Actually, there are beers that get better with age, even a few years. A trend now is to age high alcohol content beers like stouts in bourbon barrels before being bottled, and can be stored even longer at home. IMO they don't taste the great when they are young, too sharp and the alcohol taste is too strong. But they age like good wines.
But I do get your point, that beer in a beer fridge in my kitchen won't stick around for years. That's what a cellar is for.
