Hmmm, my fault... I was getting too philosophical (thinking 3 steps ahead and need to focus on the first step) and seemed to have gotten off point and may have caused some confusion... Did you look into the distinctions between personal and private property? As you used what I would call personal property:

"With ownership we are able to enjoy the fruits of today's labor tomorrow, without someone else coming along and taking away from us what we have produced. "

To protest my notion of private property (which would be the ownership of the land itself not your improvements upon it... )

Trade can absolutely happen with personal property. Trade, however, cannot happen with private property as its ownership is illegitimate. (my car analogy was just an analogy to describe an idea... It would have been better to use land/whole forests/etc... which is what I was actually referring to).

Fruits of one's labor fall into personal property (or one's homestead rather) Thought this can easily be expanded to other enterprises.

"I ascribe rights of ownership exclusively to adult human beings. (Not in virtue of belonging to our particular species, but in virtue of being rational beings). Ownership is all about deciding over that which is owned, and "nature" cannot make any decisions."

To this, I fundamentally disagree. But my path to get to my conclusions was long, arduous and outside the realm of any 'logical' 'rational (aka ratio, a fraction of truth) discussion on such a platform. So, we can just agree to disagree :)

Exploit is a word I used to denounce taking advantage of. Which is what I would say over-meeting your needs for greed... Eating food is not exploiting it. Now, mono-cropping vast swaths of land and destroying all life that once existed on it in order to make tons of money is...

Again a distinction that would be difficult to quantify.

"If this is what capitalism is, then I support it! Exploiting nature for personal gain is what we do when we cultivate land and grow crops and vegetables or graze our cattle and many other things. "

I would say we relate with nature in order to meet our needs. Look at it this way, there is a common saying in business that the best negotiators and best 'salesman' (tradesman) are those who are able to make both parties winners! That is an excellent way to build value and meet needs. This would be an agreeable relationship.

However, there are those in business that make deals so that there are 'winners' and 'losers' these often get a bad reputation in the business world. This is what I would call exploitation. When we abuse and use and profess to own the natural world and continue to make 1 sided business transactions we exploit nature.

When we relate with nature to meet our needs and meet the needs of our natural world then we can become wealthy with our abundance of our needs being met! (random example of a culture who thinks this way, the Mayans used to plant 4 cornstalks in each whole. One for the sky (birds) one for the ground (hogs, rodents) one for their neighbor (who could take 1/4 of the bounty by law) and one for themselves. They still get a bountiful harvest but in a means that everyone is a winner! They also had no concept of ownership of the land... But, that is another story.
