What If? (Old Church, New Church)

What if older, struggling churches making little impact on their neighborhood handed their church buildings over to church plants and church planters to start fresh works?

I know that some will not like my assertion that struggling churches are dead churches. But, I am sorry..."being a tight knit family of the same people for 20-30-40 years" is NOT CHURCH!! The church has a mission and that is to spread the gospel and make disciples. If that mission is not happening, than it is not the church Jesus commissioned. Very clear to me.
(I am also aware that some church planters do not have "owning a building" in their plan. That's cool too.)
So...
What if churches that have passed their fruitful season, handed the keys over to a work that is entering their fruitful season? What would that do for total kingdom harvest?
What do the people in the releasing church do?
  • If they are mature enough to release and realize that it is not "theirs" anymore....never was....then, they could stay and give their whole hearts to the vision of the new ministry.
  • If there is too much emotional baggage and territorialism, they they'd be best suited to find another ministry that they could pour themselves into.
What if? You have any thoughts? Maybe you agree? Maybe you disagree? Push this out with me.
