Like the other comment says, players build cities. A quick search says there are 81 cities with over 5m people each in the world. Most city builders were building at the scale of these large cities, so that means over 81 players would be over the population we have in the real world. If there are thousands of players, yeah, it’s going to get tight. If there are tens of thousands, there’s not enough space.

But those 81 cities take up a tiny portion of global land area.
A quick Excel import of the table from Wikipedia suggests that the "urban area" for those 81 cities is 190 K KM(2).
Total land mass on early 148.94 M KM(2).
So the world land could hold ~63,400 such cities.
It would likely take many years to build a city like Guadalajara (#81 on the wikipedia list).
