These two examples are just things put out for the right-wing press in this country to lap up, providing a nice distraction from the actual crises in the country. They won't actually come to fruition. Firstly, you could always print whatever you wanted on pint glasses anyway (and can any of the Brexit voting members of society honestly say they even noticed the Crown had gone, let alone cared?). Secondly, the weights and measures systems won't force units to be in imperial. They'll just allow imperial to be used without requiring it to also be metric. After all, everything we import from the EU is in metric. Will they print imperial on their packaging just for us? (Spoiler: no). Will manufacturers in this country print solely in imperial? No, not if they want to limit their export market. The manufacturers in the UK will probably just use imperial and metric, like they could do before anyway. Perhaps the only thing that could change is some market traders, greengrocers and the like could choose to sell only in imperial, but it would mean paying for new scales etc so I can't see many doing it except for some hardcore 'metric-martyrs'. When it comes to Brexit, a lot of people (and it seems to include the Government) are guilty of something called bike-shedding. The term comes from a fictional example of a committee approving the plans for a nuclear power plant, and the committee spends significantly more time discussing trivial things like the design and colour of the bike sheds rather than the more complicated things such as the reactor core. This is because it's easy for people to understand and make contributions to the trivial things they understand, less so for things they don't. Blue passports, imperial measures, Crown glasses, UK instead of GB stickers all amount to bike-shedding in my opinion, whereas things such as trade policy and trade agreements, resolving the supply chain and labour shortage issues, resolving issues relating to fishing and farming, and resolving the contradiction of the North Ireland border are examples of the things that get unresolved.
