A reasonable effect is also companies moving around somewhat to get closer to business rather than close to low taxes.

Why ? The payroll will increase even if profit remains the same.

The losers in the above scenario is the Irish because they'd see increased prices, lost jobs, and potentially raised taxes to offset lost corporate tax revenue.

I doubt it. Consumption tax are never popular. Instead of businesses, the people at large might migrate to Ireland for significantly low cost of living.

Ok now I'm not sure what you are arguing: are you saying this is a bad idea because it is too hard to implement?

Or a bad idea because of how it would increase corporate taxes, which would land on consumers?

I can't see how it would be a net negative for those countries that would get a nonzero corporate tax from megacorps that today contribute around zero. Even with price increases, the net effect seems like it would be positive

Its very high consumption tax. Effective, implementable but harder to get public support for. Cost of living (CoL) would rise. High corporate tax means high CoL. Every percentage increase will make it worse than last percentage. Wages would have to rise significantly. This will discourage business from moving to high-tax countries. People will likely move to low-tax countries.

Because countries are not getting new money. Old money is just cycling between govt and people.

You keep saying that, and I keep not understanding it. I realize higher prices (Companies shifting the tax to consumers) is a burden for consumers. But at the same time, if government tax revenue increases, then taxes could be cut (of all kinds: income, VAT, and corporate).

E.g. IKEA in Sweden ships 3% of their revenue as "royalties" to a dutch company, thereby reducing their swedish tax amount by over €100M/yr. If that money and money from similar companies was actually paid in Sweden, then Sweden could have a lower tax rate (e.g. 20%) and still have the same revenue. Or the VAT could be slightly lowered from 25%, to offset the fact that for a few products from multinational corporations, the products would be slightly more expensive.

Also: the argument that higher corporate tax rate = Higher CoL = bad, could be extended too. But how far? If the rest of the EU adopted Irelands low corporate tax rate, what would happen then?
