They can outlaw it all they want, they can't enforce the ban. People will ignore the stupid law. You're a white American boy, you are trained to respect authority and laws no matter how stupid they are (latinos and blacks in US are better equipped naturally to withstand this bullshit). People in the rest of the world aren't as trustful of their governments and are not inclined to abide by such laws. This particular law is not just stupid, it's designed to take away people's means of living when population already knows the government is corrupt. Rest assured that this outlawing gold together with earlier revoking of large bank notes irreparably undermines Indian government's legitimacy, which is a sure way to spawn all sorts of underground economy means and routes. So yeah, let them bring it on to the faster destruction of the top-down imposed fiat.
