Based on your analogy, people should assume that newspaper is as dangerous as new snakes?
Rest assured it’s not the case, while people have lost entire or partial collections due to improperly quarantined new snakes, no one has ever lost a snake because of newspaper. Newspaper has been used for decades by many without any issues other than leaving temporary ink mark on white snakes (goes away if you wipe the snake off, or with the next shed and the ink is not toxic)
Snakes will not get RI, IBD, OPMV, or mites from newspaper; those are some of the reasons why you quarantine a new snake away from your collection.
Now I understand some people are germophobes and it’s ok for you to be but trust me your snakes are not at risk with newspaper, they do not need to live in a bubble either, they just need to be quarantined and observed away from your collection that is IF you value your collection.
