We're not all career musos, some of us just play for fun and don't count the change; it's horses for courses. If it doesn't work for you, don't do it; if it does, fill your boots.

Surely the basic idea of bands doing the rounding up makes a lot of sense - for bands with a smaller fanbase (or maybe even no real 'fanbase' yet, just a few mates), if a few bands play together you might get a couple of hundred people together pretty easily, and that's a gigs' worth, and who knows, maybe a chance to make some real fans.
if a 'promoter' is taking a big cut, that's the silly part. Just take out the middle man - get together as bands, hire the venue and do it yourself.
