I’ve read about this concept the Indians have called “izzat” which probably explains why they have arranged marriages. You can imagine the deceitful games that might be played on unsuspecting brides and bridegrooms if one doesn’t find deceitful games out of bounds morally; arranged marriages address that.
Arranged marriages are unpopular because we value choice. For the same reason we, westerners, abhor monopolies that transform society, wreck age old institutions, remove choice and limit access to what once was free.
Free doesn't emerge from the quantum vacuum of spacetime in the realm of digital products however. It's not a innate natural right, but a choice, of a provider at a given point in time. It might change. Cost might be levied. Cost should be expecdted in free exchange. Especially as a westerner!
Aside from that - what age old institutions are wrecked by monopolies, or which ones are you talking about it? Genuinely curious.
