To me it means "being a better visitor" and "providing a better visit". The idea of living like a local is very extreme and not what I think the person that you replied to was really suggesting. The use of the term "non-touristic" is pretty common amongst non-native speakers, but it means a lot of different things.
I would only include a few of your bullets, begrudgingly, as things that I'd put in the "non-touristic" box. For example, someone if someone is trying to select a restaurant, then highlighting the more authentic options which resonate are something that I've had locals do on virtually every trip. Local people to me sometimes includes other business owners or tour guides I've encountered on the trip. I've normally done some research to find the the better spots, but a local person may know which one offers a particular delicacy that is prepared in a traditional way. They may even just know which one doesn't really require reservations.
As an example, I was in Kyoto in 2019 with my wife. For various reasons we got to our ryokan (guesthouse) later than expected. We were on the fence about planning a fancy Kaiseki meal later in the week for my birthday because only one of us is an adventurous eater. Our hosts asked us about our plans for the week, if we had food, etc., and suggested an amazing local place that we would never have found on our own. In a way it was intimidating given that no one spoke English, but our hosts had really greased the wheels with the husband and wife who ran the place. This is absolutely not the kind of setup and assistance that you get from a concierge in hotels where there is a degree of risk avoidance.
The mundane is only something you have time for on an extended trip. By the very nature of being long enough on a trip that your hair grows out, you'll likely need a trim. You may have the choice of somewhere that's easy and comfortable for a someone from a different place, or you may see that your comfort with the location has changed to open different possibilities. Of course, if you like to throw yourself into situations you can skip the haircut before leaving and try to find something when you arrive. Your personality impacts how comfortable you feel with that.
I was in Seoul for a conference a few years ago, and it was pretty obvious that there was a "tourist halo" around the Conrad and other big western hotels. Once you got outside that, you very quickly started to find eateries where they don't accept western credit cards, there's no English on the menu, and there might not even be a person on staff capable of speaking competent English.
But like, the small group I was with ended up at a place like this that did Korean BBQ: we showed the proprietor the cash we had, and basically they brought out a selection of delicious things, took our money, and that was that. I guess it's possible we might have been disappointed, but it ended up being a great experience, and certainly far more true to the experience of a local than eating in one of the hotel restaurants.
