For why, just glance at this.

(It's a Dungeon Crawler Carl-themed license plate.) Look carefully at the sticker at the top right. The tag is actually MONGON0, but it is far from obvious that the last character is a zero at a quick glance unless you are very familiar with the typeface used in Tennessee license plates.

The logical solution is to forbid issuing plates that could be misinterpreted. If MONGONO exists, then you can't have M0NG0N0 or other permutation of O's and 0's.
