4. In IPv4, it's not only perception of scarcity, there *is* scarcity.
4. I think I did the calculation and if you have 8B /48s, you still have only consumed around 1/10000th of the IPv6 space. I would use this instead of "480 years". 2^33 is ~8B. 48-33 is 15. So /48 for 8B people uses a /15. Take that down to one of the /3s we have, and it's a /12. 2^12 is 4096. So One /48 per person on earth uses 1/4000th of the currently used /3. So even with inefficient addressing this is not a problem.
The combination of "people will be using multiple ISPs simultaneously" and "large networks will be hellishly inefficient wrt /48 usage due to internal aggregation" (which RIR policies permit) this is not plenty as it looks like. A waste factor of 1000 in a network with many layers of aggregation (BRAS, POP, City, Region, Country) might seem gross, but we'll see that. Look at the HD ratio tables...
4.2.3. Can't we use the "STRONGLY DISCOURAGED" to use less than /56 ?
