IMHO the latter only legitimately applies where the comparison is tangential/apples to oranges, or if "two wrongs don't make a right" is being argued.
In the 'western' world piracy is a dubiously moral way to save money, and employed people can access the work by saving or doing a little more work like visiting a library.
But the copyright system prohibits much of the world from gaining knowledge and participating in culture. Over 1.9 billion people, or 26.2 percent of the world’s population, were living on less than $3.20 per day in 2015. This is not a particularly moral situation, and piracy directly addresses it at the expense of the western world's property rights.
Article 19:
"freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers"
Sounds like universal library access would qualify.
Article 17:
"Everyone has the right to own property alone as well as in association with others. No one shall be arbitrarily deprived of his property."
Says nothing about "intellectual property".
