Almost hit the nail on the head, but not quite.  It needs an economy, and DNMs are the critical bootstrap to a level of liquidity where the storage and transfer capacity corresponds to the needs of big money users (HNWIs, corps, and TLAs).  Right now DNMs are reeling and traffic is negligible.  But in less than 6 months there will be 20x the DNM throughput that we saw in SR1 , which took BTC to USD100, and perhaps 50% of that traffic will be denominated XMR, which will put the unit cost around $1000 by March - before the FOMO is factored in.

These are the last cheap coins, people.
