I say all four states share that corner spot (a single point) ....thus each touches the other three. No matter how narrow the lines are, the corner point is the same width. The corner point must belong to all four states or it must belong to none of them.
Imagine drawing the corner of one state with a pen of zero width. No matter which state boundary you try to trace around that corner, you have to pass directly over the corner spot (in order to start moving your pencil perpendicular to the line you just traced to get to the corner) THEREFORE: The corner point is shared by all four states.
It is understood and accepted that all four states share the common point...
consider this though... if Colorado and Arizona are in contact with each other,
it therefore creates a barrier that prevents Utah and New Mexico from making contact...
If you say that they share the common point, then they touch. You are using part of Utah and New Mexico to form that supposed barrier. Your barrier can't be shutting Utah and New Mexico out if it actually includes part of Utah and New Mexico.
