On the other hand, how bad is congestion in practice anyways? Sure it's congested, but rarely to the point where it's unusable. I don't think we need to clear out all of the spectrum from 100khz to 100ghz. If we doubled unlicensed spectrum around 2.4ghz, 5ghz, and 6ghz, we'd solve 90% of our congestion issues at the cost of barely any spectrum. Overhauling the entire electromagnetic spectrum allocations would cost millions of dollars of replacing devices; just throwing a bit more at wifi bands would cheaply solve most issues.
