It is not that 2^64 addresses are not enough for all my devices, it is that a /64 can not be divided into subnets. That is the way it is designed. A /64 is the smallest subnet. I might have designed it different but I was not involved at the time.
So... if one wants/needs more than one subnet, one needs more than one /64. That is the way it is.
It should be no problem, there is enough for everyone.
