20-year-old single me and 40-year-old married me disagree
These are two different people, many objections from the fact they disagree one ought to have from the fact that one and some random other contemporary person disagree.
And yet, a lot of our culture presumes that there are important differences between the two.
E.g., culturally we think it’s reasonable for someone at 20 to make commitments that are binding on that person at 40, whereas we think it’s really strange for someone at 20 or 40 to make commitments that are binding on some random other contemporary person.
