We should have basic local bitcoin infrastructure implemented, like bitcoin payment processors, exchange liquidity, local acceptance rate etc. Otherwise the local merchants have no point to pay extra for installing such system to accept BTC.
They have to rely on the current available facilities of bitcoin payment and when the demand through local businesses increases then more facilities will be available by different entities and if the states came for the help of bitcoin then the facilities will be more than we think and there will be no problem for us.
