It sounds like most of what you've listed, especially immigration reductions, are in the general sense things that the government now has the power to change, it just chooses not to. I'd put complaints about post-brexit policies at the government's feet rather than the leave campaign. That's not to say that prominent leave campaigners didn't mislead people with certain statements, but I also remember the Cameron-Osborne remain campaign saying that merely voting to leave would instantly plunge the country into a huge recession. People like Nick Clegg also dismissed and scoffed at (IMO) legitimate concerns from the leave side, like saying that the prospect of an EU army was a conspiracy theory, when in fact there have since been lots of higher-ups in the EU pushing for this.
