Can you offer a clearer explanation of what the BREXITors plans would be if they won the vote?
The problem is that they don't agree either. They can't say what post Brexit looks like because:
1. Gove disagrees fundamentally with Farage - Johnson's only concern is that Brexit equals Johnson PM etc etc.
2. Many of the key decisions that will shape what post Brexit looks like aren't under the control of the Brexiter or the UK, but (irony of ironies) the EU - because it is the remaining EU members, not the UK who will have the deciding say on what the relationship between an exited UK and the rest of the EU look like.
3. They aren't actually interested in detail, partly because they know that as soon as anyone credible looks at the economic forecast it isn't pretty reading, and partly because the hard-line Brexiters, who are running the campaign, see exist as the be all and end all - simply being out of the EU is enough for them, whatever the consequences on jobs, economy etc.
In most, but not all respects, this is the same as the Pro-Indy campaigners in the Indy-ref but even worse. At least largely they agreed on point 1 (albeit much of what they wanted wasn't in their control - see point 2). Also, although it was most likely that independence would be negative economically expert opinion was more balanced - so that with a following wind (i.e. oil prices remaining massively high) Scotland could have been better off - the issue was risk and lack of economic diversity and as we've seen the best case scenario has crumbled to dust on oil. By contrast there is no credible economic opinion that indicates that leaving the EU, in itself, would be anything other that economically damaging.
In fact the only report that suggests any kind of boost (when isn't specified) is (I think) from Open Europe, who aren't really a credible economic organisation, more a campaign group and they only suggest a tiny boost (0.7%), but critically this isn't actually due to leaving the EU, but due to their dogmatic desire for free market right wing deregulation policies that would make Thatcher look hard left wing - sort of Redwood plus. But that isn't going to happen even if we left the EU, because in order for it to happen we'd also need to elect (and continue to retain in power) a hard economic right wrong government more extreme than we've ever seen - it won't happen.
And actually leaving the EU isn't even a prerequisite for this theoretical (but never going to happen) possibility. If the EU member states also voted hard right economic governments this could happen EU wide. Indeed that is the only actual way their pipe dream could happen, because if the UK left, even if it had the requisite uber-right wing government, its ability to trade with the EU would be limited by the views of the remaining EU countries who will undoubtedly require adherence to certain fundamental levels of economic regulation as a prerequisite for free trade.
