Full, transparency across time makes it easy to buy people's votes, or punish people for voting the wrong way. The moment I can check that my vote was counted, and was counted accurately, then my boss/landlord/wife/friend could pressure me into showing them said record. The fact that I can vote very differently from what is socially acceptable in my social group, and there is no way for them to know is a feature, not a bug.
