On the individual points you make, yeah you are right, but these were far from halcyon days. The world was in turmoil. Injustice was rife and people were still being displaced by natural disasters, wars and famine, much as it is today. It's only that things appeared to move at a slower pace because now the news media reports on everything almost as it happens. I don't think these bygone times were that much different from what they are today, it's just that we were more insular with living on an island.
And we all look back with some fondness to a time when we were physically fit, youthful in spirit and dreamed about making our mark on the world. Life was more of an adventure, instead of grinding out what little time you have left before shedding your mortal coil.

I think you are looking to the past and seeing things through the prism of youthful ignorance and comparing it to a world you feel has passed you by, and you would like to go back there. I think there comes a time in everyone's life, where this is something we all wish we could do.
Yeah, things could have been oh-so-different, but if I had the chance to go back and do it all over again, I wouldn't change a thing, not if it meant losing the appreciation and wonder of life, I now have. Personally, I feel lucky to have made it this far.

As for all these changes, you keep pointing to, in the greater scheme of things. I don't think they really matter.
