Put another way... If I'm the type of person whom criminals will target by name, address obfuscation isn't what I need. Instead, I need a comprehensive security system (likely including body guards). Think heads of state and other famous people.
Joe Developer isn't being targeted by name. He just gets unlucky because he left his MacBook within sight of the window and didn't lock the back door.
1. Searching through travelogues
2. Waiting for one where a person is actively posting
3. Assume that the blogger is still traveling
4. Researching where that person lives
5. Hoping they happen to be close by
6. Hoping no one else lives there/is house sitting/is renting while you're out
Rather than1. Driving around looking for a place with a bunch of mail overflowing from the mail box and packages piled on the doorstep or some high value target visible through a window, regardless of knowing what the address is of the house
The good news is you're worried about nothing. However, adding a layer of abstraction to an address won't help curb burglaries.
The scenario where his blog could get him burgled is not burglars who set out to identify targets by reading travelogues. It is a burglar who happens to read the blog because he finds it interesting and happens to recognize that he is being presented with a burglary opportunity.
I think the reader feels like it matters but it doesn't. If someone is "writing from $place" it seems more immediate, more authentic, more real? When really it wouldn't matter for most situations.
How so? Or rather, what exactly do you mean here? Burglars don't want to find you personally. They're scoping out a property an determining if no one is home. They aren't looking though the yellow pages for potential victims remotely; they're driving around the neighborhood trying to get physical access.
