I think the problem is that consensus (51.9%) was made at the 30k ft. / 9km view (leave the EU). The details were left to be sorted out later and that's where all the trouble is. If the details of Brexit were included in the referendum, there wouldn't be any trouble in implementing it. But, you can bet that the ~half of voters that wanted Brexit aren't even in agreement on how to implement it, let alone trying to gain the support of all those that never wanted it to begin with. In the end the referendum was more of an opinion poll than legislation that voters could analyze and make an informed decision. I don't think you can fault the voters for answering the questions put to them. It's not like the ballot comes with a comment box: "I want independence from the EU, but I'm also concerned that you didn't think through how to implement it." They just vote Yes and expect politicians to do their job.
