I think making noise is cheaper than reducing it.

And I think this is also a problem at the habit/behavior level for people. Most people don't want to know how to set proper boundaries with people and technology and articulate what they want. Once you do that at least you can articulate what you want to come in at you or not.

Without that you get stuck with a weird one-size-fits-all policy which definitely doesn't fit for me at least.
