That's really news to me.

As long as you don't announce it to other networks i don't see an issue.

As long as nobody complains, i don't see an issue.

Or simply trying to defend the legitimate exclusive rights of usage?

OK, so it's OK that someone announces slices from 50/8, 60/8, 70/8 towards 
other networks......?

I think what the proposal contains is the ability so anyone who feels a 
victim from an hijacking event can file a report. The proposal also 
proposes any finding come from the community, not from the RIR.

Nobody is trying to create that department :-)
ARIN is a registry with 1/5 of the global responsibility.
Which law enforcement agencies are able to act against hijacks/hijackers?
ARIN at least has the ability to do something, given proper independent, 
multiple-viewpoint advice.
