This doesn't follow. The presence of a {zo'e}
in a bridi does not imply the existence of an entity for which the bridi holds if the {zo'e} is substituted for that entity. That's {da}. As an elliptical, {zo'e} assumes the value of whatever sumti is contextually implied... and if context implies that nothing fits in that place, that sumti is {zi'o}. {zi'o} is a way of explicitly expressing that that particular place is inapplicable in the current context, but {zo'e} is
not an explicit way of expressing that it is; it's a way of skipping a place and leaving its value implied.
Moreover, {kelci} is already sometimes used in the sense of playing a game, there exists text that would not break if read using my new definition {kelci}, but
would break if read using my new {kelci} and edited to fill in the x3 place with {zi'o}. From La Alis chapter 8:
.i lo nu kelci cu cfari .i la .alis. cu jinvi lo
du'u no roi lo nunji'e pu viska lo tai kelcrkroke foldi
In this context, {lo nu kelci be fi zi'o} would be incorrect. They are playing croquet.
