It'll make me unpopular, but I'm questioning some of these. The pound has been dropping in nominal value for quite some years. It had already done a 5% drop even before the Brexit referendum was called. To be frank it's fairly trivial because the desire for the rest of the world to want to hold the £ has not substantially waned and the currency (not being pegged or constrained is valuable). The price rises are real and partially a result of that, but the inflation claim put out is commonly a damp squib. There is no accelerating inflation recorded, it's simply not happening. Even if it rises by 10% and stays there that's a stable inflation rate and inflation is also a sign of economic growth.
The offshoring of financial assets might seem terrible, but in another sense it's not like e.g. offshoring of limited (officially at least) Euro financial assets. It's annoying that they do this offshoring, but the UK doesn't have to grasp them back before it can do anything in a fiscal capacity. It runs into the above where people want to hold £s, which could also be considered beneficial for the currency value.
The employment thing is a developing issue, so I'm reluctant to fall on either side right now. The stats seem to indicate that indeed the number of vacancies has risen (and labour available possibly proportionally), but the main sectors have been healthcare, public services, utilities and currently transportation. It shows two things: that Brexit really did shut off a conduit where UK companies could maintain a cheaper labour source (since then many returning eastern European EU citizens have discovered that since they left for the UK, things have improved at home and they can earn better and see families/not be an ex-pat). So the 'personnel crisis', overwhelmingly in lower pay sectors, has actually been a story of companies resisting against paying the market rate for wages and reducing the quality of working conditions. They're now finding that full UK citizens with more stability than a foreign worker, are unwilling to take substandard conditions. That is the 'crisis' for a private business sector which has grown to expect easy profit and high control of wage suppression. This is likely to effect a change they can't wriggle out of and may well be a 'Brexit benefit'...shock horror.
The exports thing is 50/50. The Brexit situation certainly slows down the trade conditions in both directions, but the UK has rarely (if ever) run an export account surplus anyway (and this shouldn't be relied upon). Exports are also a cost compared to imports which for a currency sovereign is the mere exchange of issue for actual goods! The loss of some imports and the reduction of some exports can have a knock on effect for stimulating both domestic production and domestic consumption. Which is by no means a bad thing, but requires a government with considerably more foresight and vision than the ones who keep taking power. Whether the situation significantly affects the UK's ability to acquire outside raw materials remains to be seen. I think we'll have to wait to see what happens.
The other things in the list are pretty much what they are. The Northern Ireland issue is the most problematic.
