Yes, this is why we routinely fill council homes (or public project housing) with amnesiac butlers to rearrange the residents' possessions, and also with demons for, um, reasons.

Completely reasonable things to do.

How else would we recoup our investment in the hugely expensive, unpredictable butler/demon spawning machines?

>The problem here is that you shouldn’t leave children home alone, not that it has two potentially dangerous rooms. There’s several more such rooms in your house, and you wouldn’t let them cook or use your power tools by themselves either (not until they prove they can be trusted with that anyway).

Depends on age, and the children in question. Also, if I have power tools it's because I chose them. And neither amnesiac butlers nor stochastic demons are necessary to not starve in the way that cooking food is, so the assessments of risk and basic good sense are not comparable.
