This is a nice try, however I doubt you will be able to charge those
who de-aggregate prefixes and thus cause the vast majority of
the table growth. At the end of the day a lot of these
de-aggregation results from "security concerns" since 9-11.
You may try to charge Mr. Bin Laden, however there are other ones
in the queue, too.

To keep your network running, you may either:
1. invest or
2. filter those redundant de-agregated announcements
    (e.g. don't take a /24 with the same AS-path as the /16
     it is contained in)

However, I know the second (filter) approach _will_ cause your
company which pays your salary loosing business, as your company
is an transit ISP and thus your customers router will prefer the more
specific of your competitor supplying the full table.

This should answer the question:
# If we accept argument that we should, as a community, advocate no  
# smaller PI assignments smaller than a /24 because of table  
# filtration, what happens when the table grows to the size that  
# operators start to filter on longer masks ?

This won't happen, as doing so will cause loss of business for
those transit networks which do so.

Sadly enough, you should also face that there is nothing, really
nothing, that the RIPE can do to stop the table growth influenced
by other regions in this world. If the buzzword "security" comes
up with large US telcos, this is the end of all discussions in these
days.

The only thing restrictive policies limited to the RIPE region, as the
PI /24 issue and the v6 200 customer rules cause is:
- Local ISP's homed in the RIPE region only will be less competitive
  compared to international ISP's.
- People will ly to the hostmasters :-(

We should not make policies which cause said disadvantages
without having any significant advantage.

Oliver
