Everything has its cost; it's up to us to ask, is it worth it.
Is it worth two dollars from every taxpayer to provide a free park system for all to enjoy, rich or poor, wearing a tie or a pair of Daisy Duke's? If all taxes and spending worked like private enterprise, you may as well toss out the government "by the People" concept.
As for State Stores they need not dissolve the monopoly to begin to allow private concerns to sale wine and spirits. All you need to do is modify it, limit the duration of the expectation (to protect business investments that might be made), and see how it works for ya.
Make the private businesses purchase through the state monopoly and retain the revenue, while divorcing the gubment from the hassles such as paying a living wage, providing medical benefits and pensions for employees.
I don't support this, I'm just saying, for those that do, there are alternatives to complete divestment.
