If it's free, miners don't need to send the transaction fee back because senders would not even add transaction fee to the chain. Nothing to return. Is possible to send Bitcoin without fee? I'm not really sure, fee is like a fuel and every car needs fuel to be able to run. Not sure about zero fee but it's absolutely possible to make the transaction fee near zero, unfortunately there is always a fee war. Some people agree to pay more fee to accelerate their transactions or simply ruin the chains, make it very busy so other people will move to other coins. This is the problem, even though the fee is 1 Satoshi, I think we would never do that because our transactions will take forever to be confirmed.

What will be the ROI of miners with their mining rigs and equipments if they cannot make commisions to the senders? I guess, fee will not become zero. Just like in a remittance center where we can actually see how much their commision or fee to the transaction. We need also to know that there is no more free in this world. We should also pay for the processing.
