Why do you think it’s reasonable for the government to be deciding how much private citizens can drink? Would you support a country wide policy like this regardless of whether someone is in lockdown or not?
Is 'the line' that is being crossed 6 alcoholic beverages a day rather than 7 when it comes to the government infringing on peoples rights? Confining them (at their own expense) to a small room for 2 weeks gets a free pass?
