Hold up, dude. You just accused him of "liking the +1 treadmill", when in the post you're quoting, he talks about removing +X magic items from the game entirely. Can you explain that, or do you want to edit?
Further, as we're discussing 5E, by and large, why are you bringing up "selling X to fund Y", which is, AFAIK, not present in 5E? That seems to have nothing to do with what he is saying. I get that you dislike it, but it doesn't seem to make much sense as a response to his post.
Sure. He said "as a GM, on balance I prefer the 4e approach to mathematical bonuses because I prefer the tightly bounded accuracy that it tends to generate." So I responded to that. Afterwards, he comments on removing it to keep with 5e's low number math, which is his prerogative also.
Why I bring up the "selling X to fund Y" is that since its not present, a player cannot command whatever magical gear he wishes. If the DM doesn't want bracers of armor in his game, then the PCs don't find them. Nor now is the DM obligated to give them up to keep the math in check. These bracers are powerful, the kind of thing a PC will treasure due to them being equivalent to sorcerer dragon scales or hide armor. They're not the latest in the scaling math that will be discarded with the +4 bracers come along (or sold and used to fund the purchase of +4 bracers later). Likewise, a suit of mithral chain is going to be a rare, wondrous find that a player will remember, not a no-brainer purchase because the PC has 10th level starting gold and its the best mechanical light armor.
