In that case, how do you make a random-access wrapper around

You don't. If you could, they wouldn't be an input range.
Wait, what?
I don't see why you _shouldn't_ be able to create a random-access
wrapper that lazily reads as much data as it needs to, in order
to satisfy a random read.
i.e. I see no obstacle, at least conceptually, other than the
fact you're saying you can't do it.
