Paul, from what I'm seeing the opting out of public school kids are getting every bit as much socialization as the local school kids, maybe more since they are not spending time in regimented rows looking forward.
Decentralized worship isn't necessarily sitting in front of your computer screen or tv, either. Rather than reading a quarterly for SS, then getting together in a brick and mortar church to discuss it, here some are reading the lessons on-line, doing some deeper digging on their own through the web or through extension learning or old fashioned paper books, then getting together maybe over a meal or service project and continuing the discussion face to face.
As to worship, those that resonate best with the music portion might be getting together other than 11:00 Sunday morning for extended time of praise and worship or hymn singing/playing. Those that resonate best with the sermon portion and want more than their local church offers may be already getting more sermons on line than off.
I don't disagree that we are meant to worship "corporately." But with todays flow of information, I suspect that may be going to look very different than it did say 50 years ago. We may be "getting together" through electronic media more, and doing other stuff than what we do now during that time we are together in flesh and blood.
There was a time, at least here in the USA, when most were illiterate farm people. It made sense to meet late Sunday morning, after milking and egg gathering and feeding, etc and after mama had a chance to put the proverbial roast in the oven. Stores and shops were closed on Sundays, meaning just about everyone who wanted to be there could be there. I would venture to say the teaching, preaching, and singing had a different cachet and to some extent methods then. (Lining out, for example.)
We didn't toss literacy, toss printed media, and all refuse to move to the city. (Just some of us like me on the city part

We learned ways to see those changes in the wider culture as tools and blessings.
Now we face some different challenges. How do we use these new things as tools and blessings.
They won't go away, and not everyone is now free on Sundays.
How much and how do we adapt and how much and how do we refuse to do so?
