I admire your attitude, but honestly, unless you have some serious backing you will get chewed out and spat out - I did just manage to unflag a post by a margin of 3 cents recently, but it's only a matter of time before the censors have bigger wallets.
I like to think that Steemit users are not just contributing for money but because we like the idea of not being censored. That is what makes me believe there would be backing to combat censorship by way of flag neutralization. It would be very difficult though, I admit that.
