Its not like I achieve my current projected seniority at 65, then get to work two more years at the top.

It is not a good deal for the majority of the seniority list.
The “you get to work two more years” argument is weak. It’s like winning a pie eating contest only to learn the prize is more pie.
I prefer the “you don’t have to wait two more years to (upgrade/fly widebodies/do Caribbean turns/etc.)” argument.
