I'm going to argue with you.
I can't defend Yahweh Cloudrider's actions, however. I'm forced to be pedantic.
Holiness is merely a measure of proximity to Yahweh.
That which is not holy - or sacred - is profane (literally meaning
before the temple, pro- -fane, which is probably better translated to
outside of the temple). A holy thing or place is just one that has been separated from the mundane or profane for use in divine rituals or the like and it could be 'desecrated' (or de seperated) by contact with mundane, profane or sometimes referred to as 'impure' or 'unclean' things. It was usually therefore placed in the Temple where it could be spatially close to Yahweh the Undecided, in the Holy of Holies where only the Aaronite priests could go.
Yahweh then, is a singularity of holiness. As per Leviticus 11, the children of Israel are instructed to be holy because of this.
The question isn't, I think, "What gives God the right to be 'holy'?" any more than "What gives light the right to travel at approx 300,000 kms
-1?" is a right question to ask. The real question is - if holiness is about aping Yahweh "The Butcher" Plaguebearer and trying to be as close to him as possible...why would anyone else
want to be holy, and proudly proclaim their quest?
Erm - but that probably wasn't really pertinent to your point.
