I think you missed my point that there is no way you can ensure that 
A Random Network out there will accept any/all /48s from your /32.

Router memory is costly, and deaggregation eats up costly memory to
the point that people are forced to decide between "I need to buy a new
router, to carry someone else's deaggreated prefixes, which I'm not
paid for" or "just drop /48s, lots of money saved".

Your transit ISPs are paid by you to accept and propagate what you
agree between each other.  Most other parties are not contractually
bound, and as such, free to do what is reasonable for them.
