Clearly I didn't mean Rep. Amash just sits around and votes "no" on everything. But his only "yes" votes are on symbolic bills like repealing Obamacare. If it involves spending money without offsets, he votes no, with no exceptions. Seeing as the bulk of Congressional governing involves how to tax Americans and then spend those taxes, his voting record involves a lot of saying "no."
I appreciate his reasoning for a lot of his votes, and in isolation, his arguments sound very valid to me. But you can take a principled principled stand and make the best compromise you can to move things towards your principles, or you can just try and prevent anything from happening that doesn't align 100% with your principles to begin with. If you're just going to vote against everything except the occasional symbolic vote to on bills that ensure ovums have the right to carry assault weapons, then this doesn't strike me as actually governing.
