If we give every household on the planet a /48 (approximately 3 billion /48s), we consume less than 1/8192 of 2000::/3.
There are 65,536 /48s in a /32. It's not about how available 2000::/3 is, it's hassle to keep requesting additional PA space. Some ISPs literally have millions of customers.
If you have millions of customers, why get a /32? Why not take that fact and ask for the right amount of space? 1,000,000 customers should easily qualify you for a /24 or thereabouts. If you have 8,000,000 customers, you should probably be asking for a /20 or thereabouts.
... and paying sixteen times as much in assignment and maintenance fees. See the problem there?
It's not rocket science to ask for enough address space, and, if you have the number of customers to justify it based on a /48 per customer, the RIRs will happily allocate it to you.
Yes. However, I don't think the RIRs are as willing to give out address space for _potential_ customers, e.g. if a telco or cableco wanted to assign a single block to each CO/head end to account for future growth. OTOH, you can get address space based on a /48 per actual customer, then actually assign a /64 per potential customer and have enough for massive growth.
Why waste valuable people's time to conserve nearly valueless renewable resources?
By creating artificial scarcity, one can increase profits per unit of nearly-valueless, renewable resources. See also: De Beers and the demonizing of artificial diamonds.
