I think Locke was correct when he stated that the basic human rights are 'Life, Liberty, and Property' and Jefferson did a disservice in his paraphrasing of Locke.

It is possible to have a societies where there is little concept of personal property so it is not a basic human right.

You have to pare things back to the bare bones of do most people feel morally wrong doing something.
If they don't then do not let somebody pass a law that makes that thing illegal.
By sticking to the principle of having laws that uphold moral views you will have good laws and avoid manipulation of the legal system for the benefit of a few.

What is regarded as moral will change with time and will vary from place to place and laws must be adjusted accordingly.
