Based on the comment about

https://en.m.wikipedia.org/wiki/Raphide in agave can be toxic. And the fact that it is only sold in paper thin strips. My guess is the vendors are aware that it is poison but in those parts of the world life is cheap and money is hard to come by. So they just ignore this and carry on selling it. Anyone asking might be there investigating the cause of some of their health issues.
