I've mentioned plenty of times under ideal conditions. If the condition is as you say (where there is known massive interference) I'd say that's a good indicator to either 1. figure out what the interference is and whether it's possible to mitigate it or 2. Switch to a hard link. This is very much the right tool for the right place problem.
For a majority of users wireless is definitely sufficient and that they can tolerate a reasonable amount of disconnects/drops/latency spikes. I'm not saying for every scenario wireless is a good substitute, but it can definitely handle certain scenarios good enough for home users for a fraction of the cost.
Besides, if I'm not having any major sources of interference now but somehow that develops later, that's no different than getting a congested link at peek hours, or a faulty switch somewhere along the path 2 years down the line. It's just another form of network disruption, those can develop in the same way in hard links.
Side note: I've done work over ssh and webapps with a constant 200-500ms latency and periodic disconnects for prolonged (months) periods of time. It is absolutely usable though a bit slow. I've even played PvP in MMOs (SWTOR, ESO) with those network stats back in the day and still managed to do well enough. People overestimate the quality of Internet service they need all the time.
