Sorry but last sentence when you write about "weeding out":

There will always be new scammers
There will always be new victims

The best way to mitigate against fraud is intrinsic mechanisms such as:

Bad listing of wallets: cannot send to and cannot received from.
Labeling of coins: coins that have gone into a bad wallet will be labelled unless they go into a good wallet first to remove the bad label.

Things like who gets to label a wallet bad and who gets to own the good wallets and how will that work decentralised: i think there is alot of smart people to do this, but I do not see how this is any different from a couple of companies with proven honesty records (say the likes of Standard & Poors, Moodies: but those are corrupt in core and substance) doing the labelling.

You do realize that bitcoin was created to avoid this type of thing?

Nobody wants some entity deciding whether you get to spend your coins.

If you think blacklisting would help stop scammers you're kidding yourself. They could easily avoid it by immediately dumping for fiat.
