Rules and technicalities are extremely important to the EU. The EU exists by virtue of a set of treaties between the member countries. Legally binding documents that require the EU to adhere to said rules and technicalities.
The general EU position on rules is also deeply undemocratic in the sense that the unlimited commitment was not properly communicated or admitted to at the time all this was put into place.
What we wanted out of the EU was a consensual free trade arrangement not to support an expansionistic political project that ultimately wants to disolve it's constituent nations.
Then if you break it down, there is the question of eurosceptics. Where is their influence? Have they ever successfully reigned in the EU or got it to reverse anything? They are represented in the parliament but it is a toothless/show organisation.
