When David Cameron (former leader of the Conservative party) called the EU referendum, he did it principally to quell dissent within his own party That's the current narrative of EU loyalists but it's not at all correct. There had been a eurosceptic wing of the Conservative party for decades. The referendum was put into the Conservative manifesto in 2015 because of the rise of UKIP which was making a similar promise - that's what changed. Putting this policy into the official policies of the party converted UKIP support into Conservative support and allowed Cameron to win a majority. Having promised to do it and won an election partly on the back of that promise, they then proceeded to organise it. With respect to Cameron having no plan, I agree that was quite stupid of him. Refusal to contemplate the possibility of ever leaving is one of the big problems EU ideology creates in people. Convince yourself it's unthinkable and you won't think about it. But it's not true that "the Conservatives" had no plan. The pro-Leavers certainly did and still do have a plan: leave the EU whilst negotiating a reasonable future relationship that involves compromises on both sides. So the idea that there's "no plan" is another nonsensical bit of narrative. What people mean is the "plan", such that it is, heavily relies on the EU being willing to negotiate and they aren't. As for your last point, the top reason cited by voters for why uncontrolled immigration is a problem is pressure on public services. Being able to limit the numbers of unemployed and poor workers doesn't help with that, therefore, I'm not sure why you bring it up.
