Part of your attitude boils down to: I wish all these shady, ignorant people would stop living their own lives more privately because it makes my life slightly less easy. They're probably criminals anyhow. >The only ones who gain are business owners commiting tax fraud or people doing other illegal activities, which I condemn, and a cash free society would make them unable to doge taxes anymore making it fair for everyone. Define illegal activities. Also be aware that very random things can suddenly be made illegal for very corrupt or self-interested political reasons (australia and Canada spring to mind here more recently, so too does Russia to a much greater degree). The ability to fight back against overreach by society's single most powerful entitiy, the state, be it with cash or some other means of defiance is fundamentally a good thing and has been throughout history. At the very least small time tax dodging and grey market deals are a much less historically and fundamentally evil thing than governments overusing their powers for repressive ends. Also, tax evasion in a fully digitized, cashless society would happen just the same, but it would now be done only by large companies and the very wealthy, who have the pull to buy their favorite laws, politicians and special exemptions. Your claimed individual, middle or lower class tax dodgers matter much less. What will matter however is the inability of normal people to keep their heads above water because they can no longer hide certain things from irresponsible tax collection or onerous regulations. You seem to think that more easily catching a few tax dodgers and making the misery of having no escape from taxes more "fairly" distributed is a worthy gain in exchange for a total surveillance state that has the tools to control you at any time of political winds shift.
