thats only true in theory really, because there are many ways to go around the same blocks. eg , by simply storing ur wallet node remotely. nobody said that there is something special about the traffic, just that the system is set up in a way that does makes it impossible for governments to effectively stop you from enjoying ur rights to freely transact.

All you have done is restate what you wrote.

There is empirical evidence that this traffic can and does get blocked. Furthermore, many cloud providers stop this traffic.
