I disagree with your first premise.
You are saying there are rarely any reasons to change, therefore, there is no reason to change at all.
That is not what I said.
I said:
Most of the time,
people are extremely resistant to change,
because there is no reason to change at that time,
because there is rarely a reason to change.
Taken piecemeal:
Most of the time, people are extremely resistant to change.
Why are people resistant most of the time?
Because there is no reason to change at
that time.
Why was there no reason to change at that time?
Because there is
rarely a reason to change.
What does it mean for there to rarely be a reason to change?
It means that most of the time there is no reason to change.
What is the consequence of this?
Most of the time people are extremely resistant to change.
