> we do such a great work maintaining top quality questions

You don't. Straight-up. You may think you do, but SO utterly fails at this.

In almost all cases where i end up on SO in my research the accepted answer is trash, and the one below it is the real one.

The accepted answer is decided by the person asking the question - I'm not sure SO moderators are allowed to change an accepted answer(at the very least, they're heavily disincentivized to do so). I think your example is a case for more moderation, not less.

I'm not saying less moderation is needed, but that the moderation itself being done is low quality.
