I'm a miner myself and I know that tx fees are important, but the current level of tx fees cost and tx confirmation speed fights the idea about bitcoin making fast low cost money transactions possible. Wasn't this one of the original ideas?
To start, yes. But one cannot forget that Satoshi himself had stated that eventually 0 miner block rewards and only getting the Tx fees is Bitcoin's end-game. That is what the halving's will lead to. Tx fee's MUST increase for the remaining (mega) miners to survive at that point
