Transaction costs are already a significant portion of mining income. I suspect even by the time of the next halving they will already be a greater proportion of miner income than block rewards. Lightning transactions will change all of this. By the time we are talking about large lightning transaction commits, we'll be talking about 3rd layer solutions. Bitcoin could be at a reserve currency level, where individual transactions are significant.
