It also Doesn't mean you have to attend every week (you don't) ...simply whenever is good for you!
We send our children to beavers & cubs in order that they meet new people, get to grips with life-skills, outdoor pursuits & better ideals which will stand them in good stead over a lifetime & influence others in a positive manner thereafter.
Ultimately it stems from good guidance from people just like you.
(besides you can always catch up & rewind with a missed episode of "Eastenders", "Corry" on repeats, but a child lives in the here & now ...no rewind button.
