Having used these systems in theatres/live events while I was at Uni I fully agree. These systems are amazing.
The reason is very similar to landlines. A dedicated board in each station that shares three copper lines with every other station. In this scenario you cannot beat analogue.
The ease of setup is also fantastic. All you need is some XLR cables. At some point on the line you need a power supply, which usually acts as a signal splitter so you can have lines going in different directions. Then just plug everything together.
