I suppose that might be true, but we can imagine a situation where there is no choice in the matter:

If network security cannot be maintained without sufficient inflation, then it surely it doesn't matter how philosophically wedded some users are to the 21m cap. It would lead to a hard fork, with two resulting coins:

1. An unchanged 'Capped-supply Bitcoin' 2. A new 'Permanent-subsidy Bitcoin'

Given a total breakdown in network security of the 'Capped-supply Bitcoin' (and its associated collapse in value), we would expect users to deem the, still secure and therefore higher value, 'Permanent-subsidy Bitcoin' to be the 'true' Bitcoin going forward, no?
