Yes I would prefer having to be able to not rely on specific background noise. And it looks to me like most of sleep issues are the consequence of unhealthy habits (too mich screen time, too much blue light in the last hours of the day, too heavy dinners, or too close to bed time, not enough physical activities during the day, not enough sexual activities...) so I would rather treat the problem before the symptoms.

It also seems kind of potentially antisocial/annoying behavior if you share yoir bed with someone.
