> Do you think it's practical to put dozens of antennas on every residential property?
Yes, high end cellphones already have 8x8 mu-MIMO. It can be in an array and isn't like putting 12 separate antennas in different places on your roof or anything. Starlink (phased array, different tech) has hundreds of antennas (https://www.youtube.com/watch?v=iOmdQnIlnRo&t=36m30s).
You might be thinking of like TV antennas where they often were much bigger due to the longer wavelengths involved in VHF.
Even if it were big, many many rural homes used to have those crazy big 80s/early 90s c-band satellite dishes just to get more TV channels, and for someone with a poor internet connection I could see them even putting something like that big up if it were required.
