> Imagine you didnt have law on shape and voltage of ordinsry power plugs in a house, and if you buy a samsung power socket to ibstall in your house, you mist buy samsung fridge and samsung washing machine and samsung hair dryer You seem to be conflating the wall socket with the on-device socket. I have several AC powered devices that use the same wall socket plug but have different on-device sockets - some with very different shapes. Even a single manufacturer may require different power cables: the original PS2, PS3, and PS4 all have different and incompatible power sockets and cables (squared/polarized 2-prong, "standard" 3-prong, and figure-8 2-prong, respectively). US homes often have 220V sockets for large appliances (electric clothes dryers) as well as 110V sockets for smaller appliances (handheld hair dryers.) The sockets/plugs/cables are different and are not compatible. As I understand it, every iPhone already comes with a charging cable in the box that plugs into a standard USB C power socket. Already better than anything with a wall wart power supply. But I'm pretty much in favor of addressing the absurd proliferation of incompatible wall warts and other DC power supplies, even though they plug into the same wall socket.

  Perhaps that's a clearer version of what PP was trying to say? But the analogy doesn't hold up well, because: 1. There are currently several kinds of wall power voltages and plugs/receptacles commonly in use the US. Notable examples are the various 220-240V NEMA receptacles and the various 110-120V receptacles such as polarized 2-prong, unpolarized 2-prong, and 3-prong/grounded. 2. Although there are code requirements (e.g requiring that new outlets be grounded and polarized, or requiring ground fault protection in bathrooms) it doesn't appear that they mandate a particular plug or receptacle design (?) Though the NEMA (trade association) developed plugs can and do conform to the code requirements. 3. Power cords and on-device sockets aren't entirely standardized, but it's not nearly as big a deal as if there were dozens of 110-120V wall socket types rather than the three in common use.
