if you only want a community of bitcoiners sure

There are just a few more people in the world besides Bitcoiners. We should build for them too.

"Bitcoiners" is a term only because of Bitcoin's novelty. You don't call people "Dollar-ers" because they use dollars. Stacker is reddit with V4V. Building with other monetary mediums in mind is only to the detriment of the users. Just look at how many currencies have failed. Building with those currencies as the focal value transfer is just short sighted.
