Not much in the way of alternatives for now. There are only two ways to
get static power consumption near zero: zero voltage drop or zero current.
One occurs with near-infinite conductance and the other with near-infinite
impedance. The latter is a LOT easier to achieve than the former.

Another way to look at it is that in an SI sense we're dealing with a
fairly narrow range of impedances, so there's pretty much a 1:1
correspondence between voltage and current.
