Real property = that which is material, i.e. made out of stuff that you can carry around.
For instance, if you print a computer file, the sheet of paper with the data on it is real property because it's a material thing in the world. The file on the computer is not real property because it is not a material thing in the real world that you can carry around - you can put it on a flash drive and carry that around, but not the bytes or the letters that make up that data.
Even if you could carry the bytes around (let's say for the sake of the nitpickers) in your hand without a flash drive, just the bytes, then only those bytes would be property, but the information those bytes represent is never property because the information anything represents is purely conceptual; not inherently material, but something that comes from the interpretation of material things. So I'd be free to arrange my own bytes in the same way you arranged your bytes, if you happen to publish your arrangement in any way, and you could not sue me for some bogus "copyright" claim since you have your bytes and I have mine, and you'd impinge on my right if you told me I can't arrange my bytes in a certain way because you've arranged yours that way first.
Capitalism can only concern itself with real, material property because one can only possess material things. IT is not possible, really, to possess an interpretation of something material (unless you never tell anyone, like Coca-Cola does, but they do not rely on law for their trade secret to be enforced, they simply don't tell anyone).
