Sure.

Maybe you don't have to hide a thing but even then you don't want your neighbour to know, what you're doing when you closed your roller shutter in the evening. And i don't mean a description of your activity, i mean EVERY.FOOKIN.DETAIL! Do you want your neigbours to know what your sexual habits are? Do you want to let them know what you feel, what deseases you suffer from? I guess no. Then, why do you want to let a foreigner know?

In case you don't have sth to hide you at least have sth to protect.
