We'll never get a perfect system, but I think a lot of people were drawn here by the very lawlessness of the place. That creates risk of abuse, but also creates opportunities. In a lot of cases the community is dealing with the abuse. That's just difficult when certain people control a lot of sp. Having lots of accounts may not do as much damage, but it's a worry. I plan to stick around as I still get a lot of value from steemit.
