Not all thinking time is immediately productive. Maybe 1 in 20, or 1 in 100 ideas end up getting executed and actually delivering some value. I think most people are jaded by meetings where too often the goal seems to be do anything except talk about the target of the meeting. Thinking time is a little bit like brain storming, but brain storming is goal centric - thinking time much wider scoped. Its a leap of faith to understand that growth and good ideas take a lot of time, and you won't always generate results on every attempt.
