You sound like the type of person to say to their kid "I clothe and feed you, therefore blank" as if clothing/feeding isn't your literal bare minimum as a parent.

Privacy is conducive to the healthy mindset of someone who is growing. It demonstrates a lack of trust in your child, a gross invasion of basic privacy that is afforded to literally anyone else on the planet and treats the child like a commodity/pet moreso than an individual. Arguing 'ownership' over a door is just gross.

Property is a social construct. It's just a way for all of us to make sense of living with each other.

The kid owned that door through a consensus, just as you own your things, even as an adult. If that was an illusion, so is all your property.

Point is, don't be a dick.

10 years later: “Why don’t my kids ever call or visit? It must be their fault, I will try yelling at them some more to solve this issue.”

or... here me out... trear your kids with a modicum of respect? they might turn out to be actual human beings when they grow up that way
