Drunk people and the happy bride and groom (other combinations are also available) won't notice a jot of difference between the Faith and the Gibson.

Yep, fair enough, but in your OP you seem to be saying that the discussion of which instrument is best for (gigging and) recording is pointless. Well, this discussion has informed you that if you like a lot of bass from your acoustic guitar, then a Gibson J45 is superior to a Faith. Therefore, the discussion isn't pointless.
There were two prongs to the OP: 1, is all this discussion about gear pointless? 2, do weekend warriors waste their money on nice gear?
I was answering the first prong, but to answer the 2nd, I would guess that a lot of "weekend warriors" also do a bit of recording, and for that, the right sound is very important. Sometimes you can get the right sound for £20 off Ebay, sometimes you have to spend £2000 in a shop. So, if they've gone to the effort/expense to get the right sound for recording, why not take it to the pub gig at the weekend?

Looking purely at the facts, spending £2,000 on a guitar to play 15 £200 gigs throughout the year doesn't make business sense.

You might break even on year 1 after expenses. Year two will be a big boom! Although if you're getting £200 per gig you're probably playing more than 15 per year
