Bizarre thread! I guess I don't want to live wherever "smasha" lives. Honestly, if I was THAT worried about my bike being stolen I would probably not bother owning a nice bike. There's always insurance of course. Over the years I know a couple of people who have had nice bikes (and cars for that matter) stolen and their insurance paid out without issue.
I don't personally think the concept of "trashing" your bike's cosmetic look will make a big difference, except if you come to sell it on!
