I mean arguably those are all distractions (except for the tax thing, indirectly); what really need to be fixed are the core, boring issues. The country, fundamentally, needs to keep the lights on; it needs to fix services which have been in decline for some time, it needs a credible route forward on pensions and other funding issues (but pensions are the scariest) and so forth.
A big part of the problem with the UK is exactly that; since 2015, the UK has been lurching from crisis to crisis, and more or less ignoring actually keeping the country running (keeping the country running is boring, Brexit is not boring, and so on).
