It is complex, but things like Dutch farmer protests are not so connected to the economy. There are other factors, like covid, but the lack of growth, exports and inflation far higher than the rest of Europe indicates problems which affect the UK, predominantly. So much for sunlit uplands.
Also, the indications are that people are dissatisfied with Brexit on the whole. Whether this would translate to rejoin, I don’t know, but I suspect rejoining wouldn’t happen for years, if it ever does. It does indicate a general mood that it hasn’t been a success though.
