My Brompton weighs more than even the top configuration. Yes, it should be rolled... what of it? Even if it weighed 20 lbs I wouldn't want to carry it around all the time. And as long as it rolls on the front wheel, great.
Nobody's talking about "carrying it around all the time", it's about ease of lifting into and out of transport and carrying up stairs. The difference between 20 and 25 pounds is significant in those cases; each pound over 20 is noticeable and - for me - could make the difference in whether I buy a particular folding bike or not. Right now a 10-speed Helix - which should benefit from an all ti frame and not having a heavy IGH - weighs more than a 6-speed steel/ti Brompton, not itself a notably light bicycle.
I'm sorry, if you're going to go after Brompton with a titanium frame, you gotta beat 'em on weight.
