we can't make, transport, or deploy metal films that large.

Come back when we've mastered the few square kilometer solar sail in 50 years. We've had bad luck with even test models so far.

Also, for scaling it up a million fold, you'd need to mass-produce the films in orbit using ISRU. Again, come back in 50 years when we've developed such technology.

And yes, this is a fine reason to fund and develop ISRU and solar sail research! Baby steps...
