I'm not so sure.
"Piracy" isn't a well defined legal term, so I'm guessing we're talking about copyright infringement here.
But US copyright primarily extends from US laws, which are hard to break if you're in a foreign jurisdiction.
Treaties like the TRIPS agreement extend copyright (and other IP) rules and enforcement to foreign jurisdictions, but it's not altogether clear that TRIPS would require every jurisdiction to prosecute someone who receives a stream from Netflix through an additional hop. (In fact, it obviously doesn't apply everywhere, as some jurisdictions give complete waivers to copyright infringement for personal use.)
More to the point, with streaming, it's not really clear the user has made any copy that would be required for the violation in most jurisdictions.
I don't know the situation in Italy, but it's at least not a foregone conclusion that using a VPN to watch Hulu or Netflix violates anything aside from a terms of service agreement. An unenforced TOS provision hardly has the same legal heft as copyright infringement (unless the CFAA is thrown at you, but that's a whole different animal...)
