In India, in particular, anyone can buy antibiotics, and they do, whether they need them or not. This problem should probably be addressed before we create a problem that we can't solve.
As discussed: TB currently takes a long time to fully treat. A lot of patients can't afford a full course of the recommended combination of drugs. Even if they can, and are getting their drugs from official channels, they need to be monitored regularly (sometimes daily) to ensure proper treatment. The resources to do this monitoring simply don't exist in India (and many other countries). Thus, even if you could stop all unofficial access to antibiotics (impossible in practice), there is simply not enough funding to ensure every patient is properly treated.
This is why a shorter regimen is a key breakthrough. It makes proper treatment much more accessible (the big issue), while also reducing the discipline needed to complete a course (a small bonus).
That still leaves the nasty issue of what to do with the large number of people who have contracted a highly contagious and drug-resistant / incurable disease.
But to prevent future problems, people need to stop using antibiotics as a cure all. It is particularly bad in India since patients there can aggressively demand antibiotics from hospitals and doctors.
