Is blocking the withdrawals really the best way to incentivize governance?

When I think about it, it doesn't seem that way.

What is basically the only time you want to withdraw? Except boosting your catalyst, it's when you want to empty your wallet. So anyone who actually wants to fully empty ther wallet, they need to register for voting,, just to throw that vote power away the next instant. While people who actaully want to keep holding are basically not incentivized to register at all, only woudl need to register when they are finally done with their wallet and want to leave it.

I think maybe slightly lowering your transaction fees when you are registered might be a better incentive. The more you use the chain, the more you would be reward by registering, and also the more you would actaully know about cardano being an active user.

What do you think?
