Technological solutions to social problems only tend to work when the problems are of the type "I wish it were easier to rid people of their money".
Agriculture. Plumbing. The printing press. Electricity. Vaccines. Fiat money itself, which is a technology that is better than the technology of barter, which is better than each person having to grow or make every material thing they need.
There are plenty of technological solutions to social problems. This is a tired trope.
