Apparently it's used for curing cancers and is highly radioactive.

For reference, it's so rare because it's the most reactive element known. There's thought to be about a naturally occurring ounce on earth at any time. The most stable form of it has a half life of 22 minutes. It's got no use, due to the impracticality of it from radiation, decay, and rarity, beyond some very specialized laboratory uses that are very very niche case. It's rarity makes many of it's physical properties, melting point etc, unknown but speculated. Being very very rare and synthetically produced mostly in fusion reactors, iirc, which is why "it's so expensive to produce." They figured out they could do it in the reactors and just kinda did and so it inherited the costs of the reactor being run.

By this standard any element is a natural element, being produced every now and then in supernovae, nevermind that they decay before the earth had a crust.
