> I think the majority of people aren't very good at flying drones. Even outside, it can take a lot of practice. I crashed and broke my VTOL airplane twice last weekend. Sighs dramatically. Pilot error. More seriously, there's a couple main issues: piloting, and recharging. You'd want the drone to not crash into anything, and remote controlling the drone with Internet-induced lag would be especially challenging. There's a reason why FPV setups for race drones use analog video still. Also, just as with making a household wheeled security robot, you can do that right now, but the automatic return to the charging base is not widely available as a commercial product.
