I know you feel strongly about this, but Steemit does need moderation. We don't want central control, so users do the moderation with the same power they use to reward posts. If they can't flag then they shouldn't be allowed to reward either as that can be abused too (and it is). Without moderation Steemit will be 99% spam very soon, much as email is. Nothing is perfect, but the freedom we have here gives us a chance to create something wonderful. I've seen cases where someone was flagged due to a disagreement and others rallied to counter the flag.
We have freedom. It's up to us how we use it.
Peace
