I agree with this general idea.
Communication for a purpose - in this case the 'human flourishing' you mention is a worthy goal and direction in a world running on crazy and greedy for many.
The world we have is the world we have created and we still have very real choices about the directions we could go in- some, as can be seen from contemporary politics, are not so good.
The manner of communication is also so important and I think you are correct to emphasise 'compassion'. I would add that compassionate ommunication starts from compassionate living and thinking for the individual, rather than being a mask to wear when it's time to do business.
I would also suggest the method of non violent communication as being a fruitful resource.
