 32bits * 156.000 = 4 992 000
128bits *  65.000 = 8 320 000 (not assuming private ASN's etc)

At least when you count the bits. Ask the routing vendors if they like
it or not ;)

Biggest question: what do you say to ASN applicant ~70.000 ?

Remember that the RIR's gave those organizations the blocks sized
per /19 and they still announce it per /24. Guess oh guess why and guess
what happens.

200 /48's. Also "RIPE" is the people and as RIPE NCC doesn't make the
rules for RIPE, what you say here is impossible.

If the RIPE membership (not the NCC who actually almost have no 'vote')
make a proposal and this proposal gets accepted by the RIPE membership
then this is what RIPE is going to do because their membership tells
them. Apparently there are either too many ISP's who want to keep the
ropes in their hands (which is what every big ISP wants to because they
need revenue) or there are not enough people who want IPv6-PI.

Greets,
