So you don't need to walk up from your bed to turn it off, as a starter.
Is it essential? Absolutely not. But it's definitely more convenient and it's hard to go back once you get used to it.
My go-to example to explain the convenience aspect is dishwasher. I'm from a country where dishwasher isn't common. And I personally never find the appeal of it especially when I live alone (i.e. very few dishes). I wash my pot/skillet immediately after cooking, and wash my dishes in less than 1 minute immediately after eating. It never occurred to me that how you need a machine to do such simple task, nor that it's easier to load up the dishes in it than just wash it. And when I say it, most of my (Western) friends look me as an alien. So I understand this (IMO very small increase of convenience) is important to people. Same principle applies to the smart bulbs.
