Seems like a bit of a reach to go from knowing which appliances you use and when, to identity theft and harassment by your landlord.
Besides, I feel like even if your landlord was able to get this info (in the US, utilities are surprisingly protective of account access), they'd be able to do much more just by virtue of having physical access to the property.
The burglary or home invasion angles I can see, but it actually working out like that seems extremely unlikely.
Only if you file suit and the court finds it enforceable. Sometimes they say you can sue anyway.
