Considering how pervasive Wi-Fi is in the modern world, there isn't a huge amount of spectrum allocated for it. Only 3x 2.4GHz 20MHz networks and 5x/6x 5GHz 80MHz networks are enough to congest the most accessible spectrum in high-density areas.
The addition of the 6GHz range in Wi-Fi 6E and Wi-Fi 7 is a welcome addition there, but it's also interesting to talk about the fact that newer modulation schemes also help to improve the efficiency of available spectrum. For example, Wi-Fi 7's 4096-QAM theoretically improves transmission rates by 20% compared to Wi-Fi 6's 1024-QAM without increasing the channel width.

Only 3x 2.4GHz 20MHz networks and 5x/6x 5GHz 80MHz networks are enough to congest the most accessible spectrum in high-density areas. In reality networks aren't transmitting all the time, so even though only 3-6 networks can be active at a time without interference, that's fine as long as everyone in the same apartment building aren't all trying to download a 100GB game update.
