1. Go back to the original aim of the EU (allowing ease of trade)
This is still the primary aim of the EU.
2. Get rid of the EU Parliament completely (it is purely a rubber stamping body anyway)
So you want to remove the most democratic arm of the EU? The only part of it we directly elect? And yet the leavers all whine about the EU being an “unelected dictatorship” or some such shit.
3. Clarify and codify the remit of the EU Commission and the EU Council - making it abundantly clear that Junker and Tusk are not the prime minister and president of Europe. We only need one body at this level and it should be a lean, mean, efficient and focused as the equivalent for ASEAN.
People who understand how the EU works already understand this. Perhaps rather than reinventing the wheel we should be educating people about what the current system actually is and how it works. But not everybody is interested in being educated or informed. You can lead a horse to water...
4. The golden rule of the EU should be "it's not about trade, it's not our business”
That pretty much is the “golden rule of the EU”, with a few exceptions such as the charter of fundamental human rights and a few justice and home affairs aspects (which the U.K. opted out of anyway).
5. Everything else is the business of the independent sovereign states.
See above.
