For all I know, computer types were first attracted to bitcoin for the pleasure of helping to test a smart solution to an old technical problem.  Then libertarians got interested because they saw in bitcoin a way to build an economy independent of  government and banks.  Then drug users and sellers adopted it as a way to pay for drugs without the DEA knowledge (so they thought).  At some point, others noticed the value going up like crazy, and bought into it as a get-filthy-rich-quick scheme.

I suspect that a majority of the people in this forum are from the latter group.  The finite supply of bitcoins is important only for that group, because it is part of the argument that "proves" that the price will be astronomical one day.  But it is not essential, even to them; that argument would have been only a little less convincing if the supply was programmed to increase 5%/year, forever.  So much so, that they are not bothered by the current 5-10% inflation rate.
