I'm Irish, usually pretty clued in on things. But had no idea this was actually being put through. (I suspected it would be eventually) I would definitely be objecting.
And it also means I can't really trust this person, because if he's misrepresenting this, then what else is he misrepresenting? ---
For what it's worth, personally I don't really object to reasonably limits but feel this should be up to the member states and not the EU, so I would object to this EU law. Ireland already has the requirement for a check for cash payments over €10k for example. That seems fine to me.
When it comes to laws details matter, as the recent Irish referenda showed. Not many people really objected to the general idea of the thing, but they did against the specifics. The specifics for what makes sense can differ per member state, and opinions differ quite a lot by member state as well. What makes sense in Germany may not make sense in Bulgaria.
