1 Ply TP exists?
Yeash, this cursed stuff does exist, its otherwise known as industrial grade shit spreading sheets.
you can find it in public restrooms that are maintained by city and state governments, however in retail public restrooms, its just a slight level up in quality since its just a little softer and less abrasive on one's "tender" places. As for the stuff in stadiums, athletic field restrooms, and public park restrooms that have toilet facilities the loathed single ply comes not in giant rolls but in standard sized rolls and dispensers that serve a single square one at a tiem.
But the stuff that comes in giant rolls are perfect for rolling your own ~ "fire crackers" that is if you have a source of gun powder to make them with. I used to make some ass kicking M-90's back in the old days. This stuff was perfect for the job. Of course you would also have to have a decent source for the fuses, as a short fuse would blow your hands clean off your wrists.
