I highly recommend the book Pandora’s Star by Peter Hamilton. They explore using tiny wormholes. They move them, poke a powerful sensor suite though, scan, retract, and close, gradually moving in on prospective planets. They have powerful forcefield to protect against anything coming in the other way. Makes sense to me.
One person can do something, but one person can’t do everything. If you are already running a farm co-op, leading a union, or so on, you simply don’t have the time to address the hundred other things you can see in the news in a single day. The point still stands, you can’t control everything, so even if you are making change on one or two points, you have to avoid being angry about the hundred other things you cannot.
