Not at all. "Now" can only have meaning withing a spaciotemporal frame of reference. We are used to operating within a single such context and our language assumes that.
Your point 2) explicitly brings up people from two different contexts discussing what "now" means.
While language that assumes a single spaciotemporal reference frame will continue to be used and to be useful, that doesn't make it useful for discussing systems with multiple frames of spaciotemporal reference.
