a geo block is remarkably effective it also reduces the amount of infrastructure costs therefore allowing more resources for the UK license payer
Yeah, that's part of the problem with streaming. For decades, people in neighbouring countries could (and did) listen to BBC radio stations via good old-fashioned radio broadcast. This didn't require any additional infrastructure in the UK; propagation of broadcast signals did the work. Also, there were no copyright issues; there is a long-standing pan-European legal principle that if it is legal for the broadcaster to broadcast it, then it's legal for the receivers (wherever they are) to receive it.
But the move to streaming is killing that. Streaming does need significant infrastructure investment to scale. And because it is "on the Internet", it has given various media companies the excuse to force the use of DRM and geo-blocking as well. Just another example of enshittification.
