I think the real issue with this article is that it's referencing God like ability. That if the LoA is real, anyone can click their fingers and hey presto, you can have it all, but that is not the point, that would mean you're like a god if not indeed god and again, that's not the point.
Being able to manifest everything at will, would make your entire physical reality meaningless, you might as well be floating in the ether doing that.
Why bother?
Many people who doubt the power of LoA, simply don't understand it.
It's a natural law, but it's not magic.
We are all one, one consciousness (even christen faith covers this as we are all from Adam, from god himself in his image) and
if we come from a power that is greater than physical reality, to experience physical reality, we must give up some of that power.
I'm god, you're god, we're all god, we're all collective consciousness, existing by choice in a physical reality that has rules, some can be bent, some broken, but there are rules.
I think the author is searching for a 'claim to fame' by opposing and at the same time not understanding the LoA.
