> A lot of people now import devices from countries with different frequencies causing a mess.

If they are already using devices that are not compliant with EU regulations, then I don't see how stricter regulations would solve this. This sounds like an enforcement issue. What prevents people from importing the very same non-compliant devices under the proposed regulations?

In fact, I can see more of this import happening as the domestic devices will now be more expensive and crippled.

You could destroy such devices at customs inspection. Currently such devices are legal. The use outside of the legal frequencies is not and enforcement is almost impossible.
