I see it as a catch-22. It really has little to no effect on the price or availability of "run-of-the-mill" products, as they stay pretty much the same regardless of sales structure. The difference really only manifests with the high end allocateds.
The bad thing about state run stores is, unless you have a buddy that is an insider who tips you off to shipments and/or holds bottles in the back room for you, you will almost NEVER find a top tier allocated bottle on the shelf. But the good thing about state run stores is that if lightning ever strikes the outhouse and you DO find a unicorn (or win one in a store lottery) it is sold to you at MSRP.
By contrast, if you switch to "private" liquor stores, you will finally be able to find allocateds on the shelf on demand at a few select stores. But they will only be available because they will be marked up on average 500%-2000% over retail. To most folks, there is no practical difference between there being no bottles of Pappy on the shelf for $200 and there being plenty of bottles of Pappy on the shelf for $2500.
