The device offers many features current lock-and-key models don't, and can be used by a wide variety of people (whereas you cant use custom locks for apartments). Your analogy above really makes no sense.
But going back to your original post, at least two of your drawbacks were wrong, and the others seemed to be nay saying for simply the joy of doing so. A DDOS attack on someones wireless to stop them from getting in?
A) Something that wouldn't have affected the lock since Bluetooth and NFC works
B) A targeted scenario that might as well be "well locks don't protect against rocks thrown through windows!
Why use a laptop to write notes (that requires your laptop to have power/working correctly) when a simple pen and paper will do? We can trivialize anything using that methodology.
I don't understand why you're so negative. It's a new product that has new benefits, and new drawbacks. The same could be said about the calculator when it first came out. You couldn't even compute logarithms on the first calculator model, but the slide rule had no problems. Most people were faster using the slide rule so it felt like the calculator was a backwards technological progression.
Should we try to innovate on the calculator or go back to using slide rules?
Great example. While the calculator is a great invention, it's also caused many people over two generations of not being able to perform simple arithmetic in their head. Of course, we're hackers and we try to keep our minds fresh by doing simple tricks such as calculating the total value on the receipt before checkout (or the ubiquitous 35% off stickers a certain Dutch supermarket has)--don't we ;) And almost nobody knows how to use a slide rule any more.
And while that's sad, it doesn't make the calculator less great.
There are more advantages to this than you realize. For instance, my father is a quadriplegic and has limited dexterity so it is extremely difficult for him to handle keys. If he wanted the ability to lock a door on his way out, it would be much easier for him to make a few taps on his iPad and be on his way.
