This is a common analogy but incorrect for software security. With software companies absolved of all liabilities for flaws in their products, it is more like the perimeter walls in your stores full of hidden holes about which you can do nothing. Random people publish information about new holes to break into your store regularly. The wall manufacturer is shamed by the public to drop patches in front of your store from time to time but does not install it. Now, in addition to running your store you have to make time to install those patches.
Even if you do all of that, there is no guarantee criminals will move to the next house since they might have knowledge of a “zero-day” hole that you or even the manufacturer does not yet know about. Or you did not get around to patching one of the new holes in your wall.
So no, this is not apples to apples.
