I have not written or even implied that. In point of fact, I wrote "The point has been made that 26" wheels would accomplish the same thing, and it would be a lot easier for tire manufacturers to tool up to make lightweight 26" road tires. On the surface, this would be true, but the reality is that the makers of 26" tires haven't done it, but the makers of 650b tires have, so there you go."

The only even halfway rational opposition to 26" from 650b supporters that I have seen argues that 26" appears too small on "normal size" road bikes. IMO this vaguely true, but one has to look pretty closely and be fairly picky for it to be important. If the manufacturers wanted to turn out lightly constructed road tires for 26" I think they would function pretty much identically to lightly constructed road tires for 650b. But they haven't, so the rest is so much pontificating and theorizing.
