"But alarm systems don't prevent theft, they just restrict it to the better skilled thieves. If anything, weakening alarm system open theft up to the lower skilled thieves which makes things more equitable, not less."

Man is not a solipsistic atom (though we can, to our own detriment and misery, choose to live self-absorbed, uncommitted lives). We are social animals that depend on a stable social order and a common good. That's why immigration is best done in a controlled manner so that the rate at which immigration occurs doesn't outpace and overwhelm the rate of absorption.
