There seems to be tacit acceptance that bitcoin mining is only done for profit. I mine at a profit, though it's miniscule. But even if my mining was at a slight loss I'd continue to do so (my tolerance for loss == my tolerance for my wife nagging me about the electric bill
). I'm upgrading to ASIC even if I never make money on it. I also run a full bitcoin node 24/7, both for the same reason--they're activities that contribute positively to the network. There are other reasons too, mostly involving intense curiosity and fascination with numerous facets of the bitcoin ecosystem.
Now don't get me wrong: I'm not knocking anyone's motivations. Whatever drives you is your thing and ultimately it still contributes to the network so there's no loss of respect from me. I guess I'm mostly curious to know if there are others out there like me who don't care too terribly much about the balance sheet where mining is concerned.
The mine for profit folks are just very vocal and often quick to tell others how idiotic they are for mining at a loss at the moment.
There are allot of folks like myself, I suspect, that are mining for the long term and want to contribute to the network as you described.
So I would say I'm much like you that I don't care about the balance sheet today. But I do expect it to pay off in the long run. If not then I still had some fun and learned allot. That's worth something too.
