The 60's- there was no conection between the Mods of the sixties and "mod" revival, it's like comparing, for example, Vikings and people who dress up as vikings today. The real and the ridiculous.
You're assuming the Mod scene had completely died out by 1978 and all of it's participants had denounced it. This is just not true.
A Mod Scene continues to this day, the revival was just a moment in which it achieved greater attention, followers, bands for a short time, and then it died down again to it's regular pace
Many scenes still exists quite healthily out of the gaze of the media and public eye, and the mod scene is one of these with plenty of bands up and down the country performing at Mod and Scooter weekenders etc.
Personally I wouldn't want to attach myself to any scene or culture, or to the strict rules and regs that go with them in terms of fashion etc, so I dip in and out of the Mod/Skin/Ska scenes and just do my own thing in terms of clothes. I like to keep smartish, but not to the letter.
I've always found the Mod scene a bit of a ponces palace tbh - too much attention to detail, more style than substance, so while I like the clothes and the music, I couldn't be doing with the people too much.
My biggest issue with all the scenes is that they get a bit trapped by the past, when they could be progressive. The Mod revival, at least, benefitted from the injection of punk and it's politics, as did Two Tone and Oi, whereas today a lot of Ska bands play it by numbers, much as many of the Mod bands wanna sound like The Creation.
