While India has a moral claim to these artifacts, it will take another decade or two of growth before there is adequate bureaucratic bandwidth to provision the necessary infra needed to maintain them at home. Until then, the status quo works.

Does it really? It sounds like many of these books were purchased while they were still in print.

If anything shouldn't buying books/media this way be good for publishing industry in India at the time? (Arguably, a small impact if any)
