Could Ireland survive without importing anything?

This

Lawlessness, famine and killings in a matter of weeks.

Assuming any oil reserves stored overseas would be seized by wherever they're stored (wouldn'tblame them either tbh). Whatever you have in the tank and whatever you're willing to pay/fight for at the local forecourt is all you're getting.

Assume every home heating tank will be raided almost instantly as well!

Big lol at the "we'll just have steak and milk", how does a modern farmer reliant on diesel power for everything do anything without fuel? Genuine question, does everyone have a donkey and cart on standby? Do we have that many donkeys and carts? There'll be fights over them as well!

Can't go back to everything non mechanised at the flick of a switch, be like asking someone at Space X to work on a Saturn V!

Do they keep the gold in with the toilet rolls?

You would need to get in with an old-style traveler (used to living outside the system ) and an old-style farmer who was still using horses until the 70s and only got pumped water and electricity in the 70s so they might be ancient. Still, they have the old-school knowledge of how to do it without modern machinery. The third member of the tribe would be the kind that can make or fix anything and has a shed full of bits of everything.

Then you might survive.

How would you get cash out?

Plenty of timber and if we were really stuck the bogs we still there !

I think that's with the Nazi art.

Over the counter. Branch banking would make a revival. Expect also a return to the use of cheques to make payments.

sadly Ireland would not survive without drugs , cocaine in particular as it has overtaken alcohol in terms of revenue with drug dealers all over the country controlling towns through fear and having more money than they can bury ☹️

Generally you'll get more meat by using pasture to graze beef cattle than you will by using the same pasture to graze horses or donkeys for food. Plus, beef can be sold for a higher price because people are not averse to eating it. So I wouldn't see any reason for growing consumption of horsemeat.

However, if we raise a large herd of horses for use as beasts of burden then, after some years, as those horses reach the end of their useful working lives it would make sense to slaughter and eat them, rather than simply waste them, so there might be some limited horsemeat production. (But in that circumstance the meat would be fairly tough.)

Goats can be grazed on land that won't support other livestock, so there might be some growth in goatmeat production.

Yes, we'd survive. Quite literally, we've gone through worse. We'd lose a few comforts, but we'd get through.

It would likely mean though serious work programmes, increased authoritarianism for a while, and serious cuts to social and public services.

But we would be fine, more or less.

Both turf and timber have been cut and saved/ dried for generations.
All we have in this hypothetical scenario is a lack of imports.

No mention of there being no sun or wind .
