I'm going to say something a little different to the rest (probably). I think the point of those verses quoted below is for people to meet together to encourage each other.
In the early church they didn't have buildings or even trained pastors. They did have people who spent time learning from Jesus (the Apostles and the seventy) and people who spent time with them, that's how the early church grew.
I'm not so sure it really matters about going to what we now call "Church" as in a building but meeting together for mutual benefit is what we should think of
Another thing to take into consideration is believers in places where its illegal to meet in a church building (Saudi Arabia and North Korea for example) or countries where Christianity is legal but for a Muslim to convert isn't and the Police are watching (Egypt, Iran, Pakistan, India, and many other places).
Or what about places where its OK but family if they find out about it will kill you for converting and "shaming the family"
For me, it's important for believers to meet together to encourage each other but that doesn't have to take place in a particular building or on a particular day.
