That's not a healthy attitude. You don't have to be attached to an object to be averse to losing something of monetary value. It's like you're trying to be weird on purpose.
"I'm terrified of someone stealing my $400 TV and $600 computer, so I'm going to spend hours and hours of time and lots of money on an alarm system, guns, reinforced doors, new locks, better windows, and a goddamn bubble from The Prisoner."
[0]Pretty sure I heard something like this recently. One factor postulated was that since the price of consumer electronic items and whatnot typically targeted in burglaries has been falling, the risk/'reward' calculation of what a burglar would find in an average house versus the risk of being caught and going to jail is serving to deter potential burglars.
