The OP is talking about getting "work" done, like solving cancer. The "togetherness" stuff can be defined as entertainment. Watching movies and playing games is meaningful, as is staying in touch with friends, but these things don't make the trains run on time.
Most of us would like to survive cancer so we can spend more time doing togetherness things with our friends and family. I've never seen an argument about whether various pursuits were worthwhile or not that was itself worthwhile. Its simply a topic that doesn't bear inspection, if it puts food on you and your families table then its worthwhile enough for me.
