Yes we use it but every zap is probably in most cases breaching someones tax laws. We do so because we understand how the fiat system grants a huge advantage to governments and bankers and disadvantages all other participants whereas Bitcoin treats all participants equally. The bankers and governments also understand this and naturally want to preserve their extraordinary privilege and so have responded on all available fronts to obstruct (or simply ban) Bitcoin MoE and prevent it getting a sufficient critical mass of usage to be a threat to their MoE monopoly. The tax issue is not the only factor for sure - controlling the narrative which bankers and governments are skilled at, has been a significant part of their strategy. Bringing nearly all circulating sats into KYC surveillance and enabling the accumulation of custody by corporates where the explicit purpose is use as a speculative commodity combines to work against MoE adoption. The overwhelming narrative even within Bitcoiners is now to use Bitcoin as a speculative commodity, not as a P2P payments protocol MoE. Most people do not understand Bitcoin, or even, really, fiat, and so education has to be a major part of increasing awareness and adoption. It is not impossible but it is taking on the most powerful and wealthy global cartel in existence. It might take a while!
