They don't even do that here. You are only forced to pay the fee by law if you have a device that you use to watch TV as its aired (along with some other rules). The way this is enforced is by someone who goes round to each house and verifies you have a license. They can't force their way in. There isn't a way, as far as I know, where they can just turn your TV access off, unlike cable companies can.
A pass for international use would be a bit odd without doing something like that here at home first.
This would be actually simple. Encrypt the broadcast and require CAM for decoding. Each card has a number and while there is a payment coming for the card, the card is active.
So next time the broadcast is changing and requires updated tuners (i.e. DVB-T2 and HEVC with 4K), just require one with CI.
Everyone is happy - those, who want TV get TV, those who don't, do not have to pay.
