The purpose of an air gap is to prevent a clog in the drain of your dishwasher (at the food processor for example) backing up into the dishwasher and then entering your clean water supply. This is water that you drink from, etc. it does this by having a literal air gap in the drain.

A high loop is still very effective at this, but isn’t as full proof as an air gap. That being said, I still removed mine and replaced it with an RO drinking water faucet.

The reason some houses have them and others have a high loop comes down to where and when they were put in. Some places require it to be up to code, others don’t. My advice: it’s your house, OP. Put your high loop up nice and high and I doubt you’ll ever have an issue.

Lathe is suspiciously clean. Looks like the plaster never squeezed through the lathe which is why OP had a spongey wall. This makes me question what is holding the plaster to the wall at this point! Tearing all that plaster off would probably be a breeze, wouldn’t even need a hammer!
