I don't like these badges I bought them on impulse want to remove them from the scanner.
When will this option be available ?

You can't remove badges from the scanner, nor will Niantic do that for you. The only exception seems to be when a badge is rewarded by accident, like the case of the NL-1331 meetup badge, but if you have bought the badges normally through the store, you'll be stuck with them, and I don't foresee the option to remove them coming anytime soon.
I would not be opposed if there was some sort of option in the in game store where you could "preview badge" before buying and see how it looks on your scanner before purchasing. That way you can get a feel of whether or not you would like it. I have no idea how difficult that would be to implement.
buying a badge is just like getting a tattoo
it's my profile and it shouldn't be a problem
but you can laser off a tattoo at a price :D
We've certainly pushed this metaphor farther than it deserved. (-:
Tattoo removal is more expensive than a tattoo, and perhaps that strategy would work for Niantic as well? I would pay good money to laser the Stella badge off of my profile. It's the only one that didn't require me to do something in the game to earn it.
