I find it curious that people think that the effect of rationing (a 
temporary stop) is somehow worse than a permanent stop.

So you think we shouldn't turn down any request ever?  All requests 
should be fullfilled under that notion. Obviously, we are already 
turning down requests.

This happens whether rationing occurs or not, because exactly the same
thing happens when there are only 4 million addresses left.

There is no change by rationing. We just repeat the same process with
temporary stops.  Under the current policy, the first to get their
paperwork in order will be served.

But __Less__ harmful.

But this happens anyway, rationing or not rationing. Hoarding isn't
caused by rationing, its caused by resource exhaustion.  However,
rationing helps fight hoarding because they have to come back and show
actual usage.

Without an alternative proposal, its pretty hard to suppose there are
better ways.
