Of course. But the key point is that to assert existence in the 4d framework an assertion itself is not temporal.

Not true. There is no 'now' in a 4-d universe.
All of which is a lot easier in a 4-d framework.
Of course not, but it does enable one to distinguish between a description of change, and a changing description. JFS seems to be embedded in a framework which conflates these so badly that the difference is invisible, which is MW's point.

Bottom line: don't get intension/extension confused with temporal criteria of identity, and don't get either of them confused with set/individual. JFAS thinks that sets change, which is wrong. Sets are like numbers, they are Platonic individuals. To lose this point is to become hopelessly confused. If we speak of a set of widgets, and then a new widget is made, the SET has not changed. There are two sets, one having one more element than the other. Sets aren't the kind of thing that can possibly change.
