I think that what the Beer Volcano actually implies is that once one enters heaven, one is filled with a constant feeling of well-being. The closest that Bobby Henderson could come to describing this, being limited to his own life experience, was to create an image of a continuous flow of uninhibited joy, much like how he personally might have felt if he had an eternal beer volcano.
In reality, it could be that any sort of beverage has nothing whatever to do with it. Only a perpetual feeling of flowing bliss.
Same thing with the Stripper Factory. I would be uncomfortable around a Stripper factory, because it is not my idea of happiness. If the FSM had come to me and projected the promise of heaven into my mind, it might have been a giant castle of creativity studios because bliss to me would be endlessly painting pictures and never worrying about paying for supplies or trying to sell them. This, of course, would not be everyone's bag.
Bobby is a Regular Joe. I think that's why the FSM chose him. I assume thay most regular Joes would love a beer volcano and stripper factory. For me it would be a wine fountain and art castle. In any case, when we're in the afterlife it likely wouldn't be a matter of the physical, but a spiritual state of bliss.
Taste the truth, savor the satire, pass the pasta!
