The reason they are rarely prosecuted is that they were not intended to be enforced against the compliant sheep in the general public - but against challengers who threaten the established order.
Georgia still has around 50% sane potential jurors and there is a good chance this case is going nowhere. Compare the DC (90% or more votes foe commies) judge and jury which convicted Roger Stone in spite of the the jury forewoman failing to report anti-Trump posts.
I always wondered if Stone's lawyers asked for a change of venue. Maybe they knew that would be futile.
