You’re projecting yourself. I’m not distorting anything, unlike your posts
The UK is a large trading partner for RoI no doubt. However this is at 12% of exports. That’s not the dominating factor like the 50% to 60% of UK exports that head to the other 27 eu member countries.
If the EU did not exist Ireland’s exports would be somewhat similar as it was before it joined in 1972 - with over 60% directed to the UK.
Bilateral agreements are favored one way or the other. Multi-lateral agreements are more even. There is no “morass” - the regulations are no more than what the UK had before for instance
You don’t know that at all. Unless you really are saying that the EU was creating the trade barriers? If the EU did not exist, Ireland would have been free to forge bilateral agreements with those states that happened to have been already in the EU (then EEC) instead of being excluded, and they would never have had to pay into a bloc that simply does not need to exist.
