You choose to not regard it as property, which allows you rationalize taking it from me without my consent, kinda like religious people with their loonie book, ya know.
That's an
ad hominem. I'm either right or wrong based on the merits of my arguments, not on my motivation for putting them forth. However, just so you know, I've made over a million dollars as a computer programmer selling software directly to customers. I've sold over 100,000 copies of a certain piece of software. Piracy has always been a concern for me. I was a Libertarian long before I even considered intellectual property laws. I went into the debate wanting to find support for them, biased as I was. However, I had to be intellectually honest with myself and admit that intellectual property laws are incompatible with Libertarianism. Being that as it may, I abandoned my support of the former rather than the latter, even if it means giving up all those juicy profits.
Nevertheless, it needs not be property for it to be charity. Last time I checked labor can be given (read taken) for free, and thinking is a form of labor, unless you're going to step that far in your delusion...
The property in question is your body, which you own. Slavery is just stealing ownership of it from you.
