There's also physical limits though, and structural economic lag in terms of investment. If you look at any CDN costs globally and compare it with the number of intercontinental fiber connections between those places you generally start having a good idea that the two are related. In some places there's also just less qualified talent (due to having less ability to train people in enough universities, or just not having them for as long) and datacenter space built and extra import costs that delay everything. At some point everything will saturate and probably energy production costs will dominate (largely for cooling), but I think we're still a bit far from that.
