That's ridiculously expensive. Just launch a bunch of junk into Earth's orbit and add more whenever they try to clear it. Blockade is a good idea though.

For us humans with our current level of technology, yes. However, if I'm a member of an extra-solar civilization able to cross the void by means of FTL travel, I would have a variety of means by which I could contain a planet inexpensively. Further, if the force field has the ability to deflect photons and I decided I wish to destroy humanity passively, I would simply place Earth in permanent darkness killing off all flora, leading to the extinction of the bulk of complex life on the planet.

If you're going to handwave everything, just say magic. The prompt didn't specify FTL. An AI Von Neumann probe swarm might invade the Solar System without FTL.

"Any sufficiently advanced technology is indistinguishable from magic."

Any sufficiently advanced pedophilia is indistinguishable from Disney.
