It is true that the church is not a building, nor an organisation, meant to serve our selfish needs. But rather its aim is to worship God. I like the word in German "Gottesdienst" - meaning service to God. And while we serve God, we are being blessed by God and our needs (spiritual, physical and social) are being met. But its all about Him in the first place!
Sree, I understand your concern but I do not believe it is biblical to say:
People who do not bind with a local Body of believers will not be part of this bride of Christ. How can someone who openly disobeys the binding with local Church will be somehow bound in heaven?
Because first off, there are perhaps not local churches in absolutely every city on this planet (I might be wrong here, God knows) My point is just that you do not know the circumstances of each believer to judge about that. For example, I've read a book from Amy Carmichael, who tells the story of Mimosa, young girl, who was touched by the love of God - although the missionaries could not tell her about Jesus. But after a short conversation, her heart was so changed that she refused then to do rituals that she used to do before and was punished by her parents for that. She grew up and married, tried to teach her children the fear of God and then years later, when she could contact Amy, she was baptized. The whole story you can read in the book "Mimosa". I share this, just to say that there are people, who perhaps don't even have the opportunity to be part of a church (persecution, prison etc.)
Second, there was a period in my life when I did not go anywhere to church. And the major reason was because I did not want to become hypocrite and because I did not want to break my heart again. Probably some people can manage 'break up' with a congregation easily - but for me it was hard, and at one point I really felt like "kicked out by your own mother" - the church that should be home to a believer, in some occasions, has become a home for everybody but a believer.
Having said all that, I believe that here it's a true saying: "The exception proves the rule." Therefore, I would not judge if anybody does not go to church. But thinking that some believers in Communist countries and Muslim countries do their best to gather even with risk for their life, I would say, by all means try to find a godly biblical church. Because after salvation and marriage that's one of the most crucial decisions, I think, a man makes.
