The guarantee of uniqueness is only among registered numbers, i.e. no 
two organizations can register the same number.  ARIN, like any other 
RIR, has no ability to prevent organizations from using numbers that 
aren't registered to them.

We've seen countless times where orgs pick random numbers in 
"unassigned" space, rather than getting them from their RIR, and there 
is a collision years later when it gets legitimately assigned to someone 
else by an RIR.  Should those numbers be marked as "bad" and never given 
to someone else, so that the squatter is free to use them forever?  
Think about the consequences of that.
