Not only should you contact your representatives, you should spread the message! While I'm happy to report my gains and losses throughout the year (I live in the US and am not against taxation), I don't feel like I should be arrested if I get $10,000 in upvotes overnight on Steem and I haven't even cashed out yet (pipe dream? maybe ... some people do it).
