TPOT time paradox

so i was rewatching tpot and i noticed with income tax return document (ITRD) if he wasn't stopped it would've created a time paradox.

so ITRD went to take firey's place right but he's made of paper so he wouldn't have made the lava ferris wheel leafy made. that would mean there would have been no reason for ITRD to not let leafy into dream island. that then means BFDIA would have never happened which by extensions means tennis ball and nickel would have never had the shenanigans with the yoylite meaning one would have never given it to the recommended contestants meaning ITRD could have never gone and taken firey's place creating a paradox.
