While I personally dislike /64s and /48s (for some other reasons that 
do not need discussion here, as there are good reasons for /64 and /48, 
and I can accept these), your argumentation is still flawed.  

Everybody that tells me "we will run out of IPv6 address space!!!!" has 
pretty obviously not done the math - just count how many /48s are there, 
and then do some estimation on how many people earth can suffice, and
how many /48s per person for each of those we have.  Out of 2000::/3.

*Then* come back and tell me (with a straight face) "we will run out 
of IPv6 addresses because /48s are such a great waste".

The whole point of the /48s is that you do NOT need to argue with your
LIR.  You'll *always* get a /48 when changing ISPs, and that's big enough
for all but the largest customers.  This is why /48s are *good*.

(Unless, of course, your network is too large for a /48 - provisions
for that case exist).

You're seriously confused about terminology and about RIPE IPv6 policy.

Show me the network plan that documents the need for a /40.  16 million
independent multiaccess networks ("LAN")???  (There are some, but it's
going to be "few").
