Person 2 is first of all, hard to find, unavailable, and extremely expensive. They don't know you, and in general aren't willing to share their own personal experiences with you. The interaction with Person 2 is transactional and does nothing to affirm the importance of your suffering to someone other than yourself.
It's a little like your suggesting to have sex with a prostitute because they're better at it. But that misses the point of what sex is even for. A lot of the time we just want to be assured that we matter, that our experience matters, and that we aren't alone. But yeah, a lot of people see it like you do, and I think that makes it a worse culture.
And then also there are just less and less friends. In any friend circle there are some people that are just better to lean on. As you get older these people move away, get married, etc.
I do agree that today's generations seem to be less deeply connected than older generations. Relationships take work and vulnerability, but today's distractions make everyone feel they are short on time and make us too absorbed with the perfection of the masks we wear. Its a shame, because deep friendships are truly something to be cherished.
"True friendship is a plant of slow growth, and must undergo and withstand the shocks of adversity, before it is entitled to the appellation." - George Washington
This is an important data point and a general trend toward the cheapening of human relationships. Friendship means something very specific, and for a lot of people now it means only the superficial. Anything deeper than that is actively discouraged. I think of those surveys about friendship took this kind of friendship into account. The number of people without any friends at all would be outrageously high.
