What your mind rejects, mine finds freeing. What's idiomatic and natural depends on personal experience and evolves, as does the culture around you. There was a time in my life when I may have rejected leading commas as well, but at some point I came around to them and have never looked back. It works for me. I legitimately find it easier on my mind, and it has caused me far fewer annoyances than a comma-less last column has. I have colleagues that use it as well out of their own preference. I would suggest that insisting on a universal orthodoxy of stylistic preferences is much more oppressing to the spirit than occasionally needing to adapt the mind to the reading of something formatted in an unfamiliar style.
