When doing this process, why does it require an expansive state?

If you are talking about oxygen liquefaction it is desirable that the product is at atmospheric pressure to reduce the thickness and cost of the containment vessel. It is necessary to allow some boil off (unless a chiller is available) so that the latent heat of evaporation keeps the liquid cold and prevents pressure build up. The containment vessel will of course be well insulated to minimise heat ingress.

A Natterer compressor was a type of air compression machine which was used in early(1877) experiments in making liquid oxygen(LOX). A manuallly operated screw jack was utilized to compress air or other gasses up to ~200atm(~3000psi).
