I run the same setup for the same reasons. I also think having the TV disable itself until given network access (but waiting until after you've thrown the box away) or having prepaid 5G will come soon. It's disgusting but here we are.

I've actually come to appreciate the wireless keyboard though, it is awkward and bulky (even though it's a lightweight slim model) but the kids constantly lose the actual remote whereas the keyboard's size make losing it very difficult.
