I knew Denny's position vis a vis LODO going in, so it didn't land so harshly on my ears. Like I noted above, I am doing some things to minimize uptake of oxygen and seeing pretty good results. I view both of the other steps (Brewtan B and GBF suggestions) as merely this - (i) additives that assist chemically to guard against oxidation or otherwise create potentially better tasting beer by binding with compounds and chemicals to minimize or eliminate occasional problems and (ii) processes which attempt to assist in guarding against oxidation and otherwise improve beer quality or stability.
As I see it, there is room at the table for all of this and I think Joe was saying that Brewtan B can help with a number of different things, regardless of what else you use or process you take to make your beer the best that you feel you want it to be (though some things may counteract the effect of others).
Some additives or processes are within one person's horizon and beyond that same horizon for another brewer, who is content with his beer and feels that the additional marginal effort (be it process or additive) is beyond his needs or beyond what he wishes to undertake in this hobby without further proof of the extent of improvement to be obtained by the effort.
