Despicable.

This is an extreme view. How can we even begin to talk about desires and rights under this assumption? If I don't own myself, how can I own anything? We have to throw out the idea of property, the concept of theft and so on. Is murder even wrong in this context?

> I don't see many people claiming their right to lie, their right to fraud, their right to steal. What makes privacy so different?

Well, for one thing, privacy is neither immoral nor illegal. How are these things even related?

For example, imagine something happens which invalidates a property which must be calculated (say, a bounding box for a graphical object).

Instead of immediately recomputing it, just set it to nil, and only recompute it the next time the property is actually accessed.

This way you can harmlessly invalidate it multiple times without doing a potentially expensive calculation (which just gets thrown out by subsequent invalidations).
