Re: "So how do you solve the problems of people..."
This is probably what people said when front door locks were invented.
"But I have to remember this stupid key thing and fiddle around whenever I want to get into my house? That's too hard/inconvenient, I'm used to just popping the latch or opening the gate without all this messing about"
I can quite happily say no to any member of my family without repercussions, I'm sorry to hear that's not universal. You can offer advice, if its ignored then I refer you to my previous comment: it's somebody else's problem.
