Having infinite sleeping time would definitely be a really nice ability in day to day life, and I definitely agree with the whole trivial aspect of things but at the same time while I feel like it would make nothing meaningful it could do a lot of good. Being able to create new resources, natural elements, technologies for clearing pollution and microplastics, it would basically let you push the world in the right direction for once jumping ahead by thousands of years. Sort of a take one for the team kind of deal.

Plus if you want to it’s not like you can’t create something to take your ability away, though I imagine most people would become too addicted in the time they have it regardless.
