> Again the law establishes a rules making body that can at any time change or add rules

Please quote the exact text of the law that you claim does that. And since the law has been in force for 10 years, perhaps you can point at the website of said body.

If you say "DPAs", then...erm... perhaps learn something about the world around you? Who do you think monitors compliance, say, for food, or for construction? It just appears out of nowhere? Same here

Which body is this? The EDPB?
