Reasons and justifications are different, and largely unrelated.

Nobody was talking about justifying anything, just the reason.

I never actually asked for a reason. I only pointed out that ability isn't a reason.

You might find more productive meaningful exchanges, when you engage with actual people rather than your own straw men.

But maybe meaningful dialogue isn't important to you. In which case I have nothing more to say.

Yes? I don't think I understand what you're point is.

That statements literally means [she want's to] [because she can].
As in, the ability is driving the desire.

But that's not how it works. We're able to do lots of things we don't want to.
The desire might not come from anything identifiable. The existence of desire is it's self the reason. The ability isn't the reason.

Does that make sense? It's a nuanced difference for sure. But an important one logically.
