I think you misunderstood what I was talking about, or perhaps you're an example of it.

It means, "what if the EU starts acting belligerently to other countries like the US has?" Where, hypothetically, would someone move their data since now the US and EU are off the table?

And if your answer is "well, you see that would simply be impossible because <waves hands about EU policy making>", then I guess you're an example of someone believing that EU politics will forever remain sane.

Same situation as the US...

You mean if a EU member state does this? Then those contingencies I mentioned earlier will be used.

If you're a EU member and another EU member does that, you'd still have your data in EU, just not in that member state, if you had that.

I've literally pointed you to concrete and very real contingencies that exists today, zero hand-waving.

> Same situation as the US...

I don't know how it works there, I just know that no one in the EU assumes everyone else will always agree with you, and if you look at how democracy works in EU and in the member states, I don't think anyone has those assumptions there either.
