Tents would be so easily ransacked by the passing Kobold or Goblin ... not sure I would want to keep stuff in it. Plus with the weather we have been having ... it could easily be washed/blown away. Used as a loincloth by an Ogre, snot-rag by a giant, or home for snakes or those nasty crawling branch like creatures.
Plus if thtents were to start popping up everywhere forming little communities, it would attract unsavory types people ... druggies, alcoholics and such and drop the property values, the place would become filthy and slum like. trash laying all over the placed, unwashed tents, the smell, ugh!
See? Tents bad! *Nod Nod*
