That is part of it. But the important point is that it is not inherent. There nothing saying that you can't be protocols for that. It is just beyond what the Internet was design for many years ago, and the de facto Internet today include proprietary infrastructure run by large tech companies. But it is generally even worse then that because today smart phone don't have external ip addresses so you can't connect to them even after the initial centralized wake up. So it is an absolute regression as well.
