Not since the Tree Liberation Act was passed back in 2011, making it illegal to raise a tree into a life of virtual slavery, putting an end to "inhumane" tree farms. Still can't figure out how they got that one through Congress. We've been importing paper ever since, but that's really expensive.
Hence the move to using soy-based synthsheet for everyday hardcopies, but hardcopy is so 20th century. I mean, I'm a bit of a traditionalist, so when I bought the hardcopy of 5.75 in synthsheet is was already over $300, the Collectors Edition with imported actual wood-pulp paper was $600, and I couldn't bring myself to buy it (not to mention the Collectors Edition didn't even incorporate the Errata!).
