You're looking at it from a single transaction cost-benefit perspective but that's not how it works societally. If everyone in the society knew that cops will be in their front door steps with a warrant every time a phone or a laptop was stolen, they're not going to be stealing them from the get-go.

So to translate, there may be a high up front cost but the return on invest will outweigh in the long run (for higher value products, admittedly). Even if that's not the case, you're not valuing the societal cost at all!
