In particular - they are much less likely to always blindly follow party lines, or corporate wishes, and I think there's value there.
How would you feel about a tweaked system? All votes are recorded, but the voting record is entirely withheld until 3 months before the next election for that seat.
The public is made aware of the voting record when it matters: During the next election. But during the term, they are much less susceptible to corporate donors and lobbyists, or pressure from members of their own party.
I want the politician I vote for to more or less follow the party line on important votes. That's why I voted for her.
I also think this leads to a preponderance of "division" politics - where the goal is to find a wedge issue that forces people to pick a side.
It's poor governance all around.
(Obviously disclosing your cryptographic vote receipt to a donor would be forbidden.)
