I just watched a TikTok about how people used to plug in things to their light sockets when electricity was first becoming popular. And they kept calling the plug a light socket, what rule says it’s not a plug that screws in? And why shouldn’t plugs screw in? We have material science to make plugs and cables hard enough that if you kick the wire it still doesn’t come out. Electrical connections should be more secure. That’s all I’m saying.
My guess to the biggest reason not to do this is safety - if somebody is being electrocuted, you want to be able to pull the cord out of the wall as quickly as possible to maximise their chance of survival.
