Not sure why you're being downvoted, I'm exactly the same. House locks are already electronic/automated, haven't carried a physical house key in year. Cars use fobs, for newer vehicles there is no option for physical keys anyway. When I leave the house I take my phone, plus the solo fob for whatever vehicle I am driving. I have no desire to have a ring of multiple physical keys and fobs with me.
Because it's a wild rube goldberg solution to a minor inconvenience.
