More centralization, non-full blocks and therefore less fees, therefore less incentive to mine, therefore less secure network.
Any evidence to support this assumption?
Doesn't the data already indicate that most people pay the minimum Tx fee despite most blocks being unfilled? (They have a choice of paying nothing and waiting a couple days)
Doesn't the data reflect that Tx fees are starting to cover the costs to secure the network (now paid by interest through block rewards):

Where is your evidence to suggest otherwise?
Why would you assume people would pay 40 cents per tx fee with a full block vs 4 cents with an half empty block?
4,000 transactions per block @ 40 pennies each(Full 1MB) vs 40,000 transactions per block @ 4 pennies each(half 20MB) = 20MB block equally secure or Insecure?
Wouldn't they just not use bitcoin altogether if fees were that high? The data already shows resistance to 2-4 pennies in Tx fee's , where are you going to find the millions of users willing to pay 40 cents per Tx?
