in the abstract but in the social of the home you have to be the bad guy. While good parents manage that, the bar is too high for society in general.

The bar isn't that high at all. It's just what norms you decide to set. You could make this argument for any particular parenting decision, from washing hands before food to saying no to the next desired purchase. It doesn't make sense to special-case this. At some point you're setting rules, and it's not that difficult. Just don't buy the device.

sorry but I feel like your standards are a bit higher than the average here. The bar is, and has to be extremely low, to hope for compliance.
