Wow, beautiful writing. You know how to use words well.

Your second last sentence “it needs to connect you to the people around you in ways that are meaningful to yourself, otherwise it will leave you empty and drained” is in my opinion a key point on this debate on longlines/communication.

As with anything in live communication, relationship, friendship needs to be a two ways street otherwise it won’t be of true value for either side or won’t work in the long run.
