As far as I understand, 3 numbers are the minimum that we currently need to specify a location somewhere in space after selecting an arbitrary origin (the numbers are usually presented as (x,y,z) coordinate triplets). I'm dropping the 4th time coordinate because i'm not concerned with a specific event, but only a point at which events keep occuring as time flows.

If spacetime is quantized, then wouldn't we be able to describe points in space with fewer numbers, and thus we wouldn't actually have 3 spacial dimensions? If i simplify to a "2 dimensional" plane, we would currently need to pick an origin and then specify each point with an x and y coordinate, and there would be an infinite number of such points for any specific area. But, if there was a discrete number of points (quantized spacetime) in that same area, then wouldn't we be able to pick an origin, and go around the origin in a spiral, numbering every discrete point we encounter? And we'd be able to assign a single number to every point on the plane, instead of needing 2 numbers per point?
