We need a crypto credit union so merchants and the likes are not forced to deal with banks directly. This entity could be devoted to finding and maintaining partners with banking entities to do nothing but convert from crypto to fiat and back.
Well, even credit unions interface with fiat somewhere, whether that's a payment processor or Visa/Mastercard themselves. Those entities have just as much incentive to shut Bitcoin out, and will surely do so. The answer is to move more and more to a full Bitcoin economy. Get paid in BTC, spend it in BTC. I'm already 50-60% there (many of my dev contracts are paid in BTC, and I pay for many of my household expenses in BTC).
