My friend's parents tried this sort of punishment mindset with him when it was a kid. He ended up grounded with increasingly draconian punishments for roughly five years because of the shockingly impressive stubbornness of all people involved until they "gave up on him" after 7th grade (yes, this literally started when he was a 2nd grader). He ended up moving out on his own at 16 and dropping out of school and didn't really have a relationship with them for a good decade and a half.

I don't really have any words of wisdom from this other than never underestimate a person's ability to defy logic. It just ended up ruining the whole family's experience for a long, long time.

Edit: I did just remember something "funny" about the whole thing. My friend didn't really know how to, or enjoy, doing a lot of things that pretty much all kids did because of his seemingly eternal grounding. And he was quite literally the palest person I have ever known because he only went outside to get on the bus for school. His parents turned him into some sort of cave person lol

My parents attempted that with me, not the can-roulette part, but I was a picky eater, so in order to get me to eat new foods and expand my palate, they would give me food and say, you're not having anything but that. You're sitting at the table till it's done. While they ate food that I definitely did like.

They ended up giving up on it because I would sit at the table for hours on end and even sleep at the table. And due to the fact that I don't feel hunger until im basically almost fainting, I would basically put myself on the brink of feeling faint, which concerned them.

I'm no longer extremely picky. I'm still picky, but no longer to the extreme extent that I used to be.

And then they'll wonder why he wants nothing to do with them as an adult and why they never get to see their grandchildren and then eventually why no one visits them in their nursing home and why they die alone.

"How should I know? You ripped all them labels off, you tell me?"

What's for dinner?

Can.

Beans, and uh beans?

You do know that odd stuff happening kind of makes life worth living? This is a mild inconvenience in the moment but a story to tell and laugh about for decades. This is net positive by miles and miles.

This would be the highlight of my week. I love telling my friends about the devious shit my 2 yo comes up with this is peak rebellion.

There was also a skit on the Wayne and Schuster show about the "Super No-Frills" grocery store featuring this as one of their cost savings features.

Dog food is technically safe for human consumption.

For me at least, being grounded was the preferable alternative to having my ass beaten physically off my body with the nearest leather belt or wooden implement. I can serve my time and be free afterward, or I can make things worse for everyone involved, and still be grounded but also be physically harmed while I'm grounded.

Was this good and right? Hell if I know, man. It feels like a fundamental disrespect of someone's human rights, but also, I was ten, and it succeeded in teaching me to be less of an incorrigible little fucker.

In my house it was:

Grounded.

Grounded to bedroom

Grounded to bedroom with all toys locked away (books didn't count)

I loved reading so I mostly just stopped there and read 30 volumes of old science magazines in a row.

This is an excellent idea. Now, not only as a kid eating crappy food. The entire family is annoyed with the kid. This is a win-win

That was my initial reaction. “Great peeling, junior.”

Nah. We're making a grocery run to get new stuff for everyone else and the shithead gets mystery cans until they're eaten.

And by "everyone", you mean "just that kid", right?
