"Extremely Expensive"? I can get an Archer BE3600 from my local Microcenter for $90. Comcast is sending 6E/7 capable router/AP combos to customers with fast enough connection speeds.
If all you care about is the peak speed at short range, sure, maybe it's the right choice. But for most people coverage is far more important.
The Archer C80 has 3x3 MIMO and costs under US$40. I get 400-500Mbps over wireless (which is firmly in the Good Enough territory for many uses) with it on most 2x2 devices, plus I can install twice as many for the cost of a single Wifi 7 router to get better coverage. That seems like a win to me.
