Do you intend on shooting your house?
No. But that isn't what the rule says, now does it?
It says (at least the variation that I know and teach)
don't point the gun at anything you aren't willing to destroy. When I dryfire, I have a specific area in the house that I use, pointed at a section that if the bullet makes it through the brick, it'll go into dirt. If I put a hole in my bookshelf/wall/dirt, I can live with it. I'm not planning on doing it---but if I make a mistake and break any the safety rules, I willing to accept the destruction of where I'm pointing the gun.
I'd rather it didn't happen---but that's a different case. And your change of "willing to destroy" to "
intend to destroy" doesn't work, as that is something else entirely.
Your additional contention of:
So if the first rule of firearm safety goes against what you are trying to do, modify it until it works.
...similarly attempts to change a flat statement into something it doesn't mean.
