Good points, and it's complicated.
What the Jevons Paradox meansm more specifically, is that the cost of a good or service is reduced. Taking costs as opportunity costs (Krugman, Economics, 2008, "All costs are opportunity costs."), you're making a thing cheaper.
The response depends on what that thing is and what the relative demand is.
Printing (and communications/information in general) is, well, an opportunity for minting money. The capacity to spew more crap is pretty much endless (hence: the modern WWW). Reducing cost constraints will increase output.
The glassblowing case, and skill requirements, are one where you're probably seeing interactions with a larger, oversupplied, labour market. Offer a lower-skilled position, avail a larger pool, and cut labour costs whilst increasing output.
Stone planers meet an intrinsically limited demand, unless you can suddenly increase the demand for the product. Creating an interest in stone statuary, or stone walls, or something of the sort might work. Pet rocks, Beanie Babies, Bratz Dolls, iPods.
That's a marketing problem....
I've been kicking around other areas and interactions of reduced costs.
Reduced travel costs (railroads) made holidays and holiday resorts possible, as well as commuter suburbs. Automobiles increased these trends, and created back-seat sex (mobility, privacy, opportunity, virility...).
Low-to-zero-cost email created spam.
Low-to-zero-cost webhosting, plus copious data and ad networks: weaponised viral clickbait.
Low-cost long-distance service: robocalls, Carol from Account Services, and Microsoft Support calls.
Increased travel almost always introduces more disease vectors -- from the Silk Road to Roman highways to Columbus and the Age of Discovery cross-polinating old and new world diseases. James Burke of Connections suggested that the biggest legacy of the jet airliner age might be in epidemics. He made that observation in the mid-1990s, with hindsight on the AIDS epidemic (one "patient zero" was a flight attendent).
I'm trying to come up with a good general term for these effects -- along with pollution and systemic problems (crime, fraud, corruption, public health crises), I'm leaning toward "hygiene factors" -- things that can reduce your capabilities. Open to suggestions though.
