"While your procedures in your section/area are very sound and to be commended, there are no rules that prohibit a shooter from purchasing a membership, signing up on the wait list, paying for a slot, and shooting his/her first match at a national championship as unclassified"
"The only requirement to buying a slot or being a walk-on at the USPSA Nationals is being a USPSA member"
Shocking, but from an attendance viewpoint, I suppose it makes sense.
Happy New Year.
