Internet dating issues
Sure, there is the breakup drama, but online dating markets mean you won't have to suffer that drama sitting home watching sad movies; you can find a replacement within days.
I agree that those are two of the problems with online dating markets, but they are really just the tip of the iceberg.
Online markets reduce friction drastically in that they make the shopping part laughably easy.
Let me illustrate this point with an example that has nothing to do with dating.
A frictionless market is one that puts together buyer and seller without transaction costs.
But while online dating minimizes the heartache periods, minimizing those periods really doesn't do us any favors—we are losing periods of reflection when we might be thinking about what we did right and wrong, how we can improve as individuals, and what we might be open to next time.
It leads to stasis, both for individuals and for relationships and (turning my music example into a metaphor) it leads to music that is predictable and unexciting. Online markets assume we know what we are looking for, but sometimes we simply don't know what we are looking for until we stumble across it in a search for something else.
Let me illustrate this point by another example from my embarrassing hobby of philately—this story explains how I came to collect 19th-century postal history.
Of course online dating services can randomize their matching algorithms to supply unlikely options—but these options are always served against a backdrop in which more likely options are plentiful, easy to obtain, and on the face of it less risky.
We need the scarcity to propel us to try the unlikely pairings.
First, if it is too easy to find something you just don't value it as much.
