You’re not entirely wrong. India does have a problem with gambling and especially in Bank Nifty. I think something like 50% of options volume is retail, which is wildly high. Just because there is a gambling problem does not make it “pretty straightforward”. The courts will hopefully figure it out to their local pleasing.
Edit: I don’t think my point was clear. If you are going to allow retail in the options market, you should also be ok with sophisticated actors participating in it.
