I completely agree with you OP. Hashers, as you call them, are just another example of profit mongers that are using Bitcoin to reap whatever short term reward there is out of Bitcoin and convert it to fiat. That's Bitcoins biggest problem as far as I can tell. This community is plagued by them and even has devs that seem to fit in that category. I've always seen pool sysops as profit mongers with the exception of a couple of them. Pool operators don't help the network as much as they help themselves to network power and control. If P2Pool was implemented before the pools took control it could have captured and kept majority control of the network because individuals would have been required to learn its use to reap the reward. Sadly, it's now too late for any meaningful change.
