With one tongue-in-cheek sentence you unraveled your point lol. The difference between the ground outside and the floor inside is that I regularly clean the floor inside while outdoors remains outdoors. I don’t think people are wearing slippers so their floors will be perfectly sanitary and able to be eaten off of, it’s so that you’re not bringing in piles of dirt and nastiness every time you come inside. It helps keep your floors clean for longer and makes cleaning them easier.
My point is that there’s a big difference between coming inside with visually-clean shoes and “bringing piles of dirt and nastiness.” I observed during COVID “lockdown” when I and my husband didn’t leave our apartment at all because of his vulnerability, and there was absolutely no difference in the amount of grime I swept off our floors from the previous weeks. Nor has it increased now that we exit and re-enter. Neither my shoes nor his wheelchair tires are tracking in any measurable amount of additional dirt. What did make a difference was the Palisades Fire. We were on the eastern edge of the Warning Zone, upwind, and evacuated as a precaution, leaving our door and windows shut and HVAC off. We returned to find a thick layer of ash on our balcony and a thin dusting of ash throughout the indoors. So I maintain the outside gets in regardless. If you don’t choose to take off your shoes, wipe your feet.
