If we ever want Bitcoin to evolve from a store of value to an actual payment method we have to come up with something that does at least better than VISA's 8000tx/s and that's just not solved with going from 7tx/s to Bitcoin Cash's ~62tx/s. We have to be able to compete with every payment method out there and we should be able to handle peak throughput during sales period.
Another important factor is the 10 minutes confirmation time, nobody wants to wait for 10 minutes at the counter before they trust you walking out. We need something with instant verification and low fees and increasing the blocksize will never do that.
