I think there is a lot of truth to this actually. Admittedly I'm a little sleep deprived right now in that way that leads you reading a statement and feeling it is incredibly profound in a way you might not otherwise... but still I think you are really onto something.

Working with someone smooths out the edges well when things go poorly (if something goes wrong and you are alone it is easier to be grumpy about it than if you have someone with you to say "oh well, we can do X instead" or "It doesn't really matter"), they make the work feel seen and therefore feel more valuable. I can enjoy cooking for (and especially with my partner) but I can never be bothered to really cook for myself, even if I'd enjoy the meal more in the end it doesn't feel worth the time and energy investment when I could just slap together a sandwich or something.

This extends to hobby projects as well in a big way, perhaps even more. Sure I could spend hours painting a picture and have people say "wow, that's impressive" (this is just an example, I can't actually paint), but it feels hard to justify when I have other things I might need to do. If someone else is working on the same thing with you it makes you feel like you are investing that time in them, which is inherently fulfilling.

Even in your example of you helping your friend, once they've accepted you are helping they will feel like every bit of work they do will make your life easier. It's less intense but they will still feel like they are contributing to your efforts in someway, or at least like they are working towards a mutual goal instead of something kind of isolated.
