I'm pulling examples from actual US history. If it involves gambling (or similar) or creating alternate forms of money, then watch out. You can believe that you don't need permission, then tell that to the FBI as they are raiding your house.

you don't have to tell the FBI! you get a chance to tell the judge when the FBI/DOJ presents their case against you.

There are many recent examples of fed agencies doing aggressive tactics and getting overturned in the courts (Rare Breed Triggers or Polymer80 vs. ATF, or Apple vs. FBI for forced phone unlocks). Don't let them bully you into not building something that you believe is good for society!
