#2I am still reminded of early WiFi and ways to extend it with Cantenna or foil backed contraptions made out of cardboard.

Used a cantenna and a PCI card with modified firmware to great effect when I only had WiFi for internet at the barracks in Japan in the 00's. I was absolutely outside of the legal limits on power, which I didn't really know at the time.
Extreme contention when 250 people had 3 APs as their only connection and half were trying to play WoW at the same time.

#4They address that they were looking at the maximum unlicensed power.
In HAM circles some people do use WiFi in an arguably legal manner by making the SSID their callsign and either making the network open or putting the password somewhere public. This is because you are not allowed to use public bands for encrypted communications (with a carveout for satellite control, for obvious reasons).
I'm unsure what ranges can be hit with that setup, but I know it can be far enough that LoS due to curvature of the earth becomes a factor.
I do think just getting a wireless P2P bridge is easier and smarter and why this hasn't seen more use.

You can buy consumer wireless repeaters basically but the latency sucks

And no passwords! That's how I got Internet as a broke college student living off campus.

#7I’m pretty sure I’ve connected to a bog-standard Mikrotik Metal over a thousand feet. The surprise wasn’t that it connected, it was that the phone could transmit back.

#8Not about range, but speed. Wifi is surprisingly slow. I noticed downloading a model from the internet (Huggingface) to my Desktop (connected by LAN cable) is faster than copying it from said Desktop to the laptop in the same room via Wifi.

#9I vaguely remember some sort of stunt where they had got hold of two 3 meter dishes paired them with off the shelf wifi radios, mounted one on a pickup truck and drove out across a dry lake bed. 53 miles before signal loss is what I remember.
I will probably never be able to find the source, and my poor memory probably inflated the range like any good fish story.

Depends on the WiFi, you can easily get 1Gbps on WiFi 7 as long as your modem + access point have the bandwidth
