This is spot on, and also its worth noting there are different time/energy requirements for each of these modes.

I can text my friend in the same hobby randomly throughout the day, listen to gear reviews while I do some rote work, and shop for accessories on my lunch break.

But depending on the hobby, I might need a solid 1-2 hour block of time to really get into actually doing anything. Some are even worse if setup/cleanup or any travel is involved. And for some hobbies daylight & weather must cooperate.
