Limited block size is necessary for the long term security model of Bitcoin.

Limited block size is necessary to build fee pressure and finance POW security after the coin rewards drops to zero or near zero. Why does nobody ever mention this in the context of the big blocks vs small blocks debate ? This is by far the most compelling and obvious argument. Unlimited block size and cheap transactions simply does not work and can never work, there needs to be POW security. Why they never mention this ? via /r/Bitcoin http://bit.ly/2IZX9Fr
