Based on what I see in the Bitcoin Core source code validation.cpp file, I disagree - the subsidy has an exponential decay for 64 epochs and then 0: https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp
CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
    int halvings = nHeight / consensusParams.nSubsidyHalvingInterval;
    // Force block reward to zero when right shift is undefined.
    if (halvings >= 64)
        return 0;

    CAmount nSubsidy = 50 * COIN;
    // Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years.
    nSubsidy >>= halvings;
    return nSubsidy;
}
The critical thing to note is that reaching 0 is not when the problem occurs. Instead, the incentive for shenanigans grows as the subsidy declines in relation to fees, so probably in a couple of halvings things will start to get weird. Maybe I'm missing something.
