A lot of people voted for it as a point of 'control'. The UK might be in a pretty messed up place politically right now, but it does have full control over its laws. The buck stops with someone you can reasonably drive to and shout at. The EU was a slow and constant move into more and more centralised control in Europe.
Some of these people think this means they can influence the country more for their own gain; some think it protects them from people influencing the country unduly.
Either way, its hard to argue against brexit having given the UK has more on paper long term control, and its hard to argue against brexit being costly both theoretically and in practice, and its hard to argue that the UK wouldn't currently be better off in the EU. Its hard, but people are doing it.
