content: You've touched upon a point here I want to expand: You don't just have random people coming to your house, you have random people coming to your house, who now have your name AND address.  Does the package require a signature? Guess what they've got now, too? Here's the thing about all these companies "offering" their work to non-employees: Its turning everyone into a multi-company contractor.  The logical conclusion of this is that the next generation won't be working a single job for a livable wage; they'll be working multiple jobs for scraps that these companies want to throw their way.
