but, why? do we need more than 16 exabytes of memory?

Right. Does anyone even need a megabyte? As Bill Gates famously (didn’t) say, “640k ought to be enough for anybody”.

Joking aside, we very well may one day have more memory available that 64 address lines can handle. RISC-V’s spec does have a stub chapter for “RV128”
