Just because the benefit of being cautious isn't clear doesn't mean we
should simply throw caution to the wind entirely and go back to the "old
ways."  It seems clear to many now that a lot of the legacy allocations,
/8's in particular were issued in a way that has left IPv4 inefficiently
allocated and with lack of any agreements by the resource holders to
have any responsibility to do anything about it.

If we just eliminated the RIRs and agreements governing terms of access
to v6 allocations, IF later, we find a problem with the process and
start to run out of space, we end up in the same situation.  Suddenly we
have to form these organizations again, and institute new allocation
policies for new allocations, but again lack any recourse for all those
people that "greedily" ate up as much space as they could.

I think there's a continued need to keep an organization in charge of
accounting for the space to whom we as resource holders are accountable
and whom is also accountable to us.  Later on, when we realize we've
gone wrong somewhere (and it will happen) and need to make changes to
policy, there is a process by which we can do it where all the parties
involved already have an established relationship.

I am not going to argue your second request.  It'd certainly be cheaper
to do things your way.  I just think it's a terrible idea.
