There are multiple usages of the word.

One of them refers to tangible things, was first codified more than 5000 years ago, and is almost entirely uncontroversial.

The other was popular in 1700's France re: their system of privileges, and the people found it so onerous that they embarked on a campaign of executing nobility until it seemed like the concept was good and dead.

We can use the word however we like, it's just a word, but if we conduct ourselves as if they're the same sort of thing, which France was doing at that time, we're in for the same sort of pain.

So what I'm saying is that its a bad idea for us to let data be property.
