There should be an age of "supermajority" where a bunch of rights revert to being similar to the age of minority.

And yes, I too have parents of that age, and yes, they're still mentally sharp.

Which of my rights do you want to take away without caring if I'm impaired or not?

[jjani]

The rights of minors are taken away without caring if they're impaired or not. At completely different ages across different territories, showing how it's comparably arbitrary if so.

Voting should be weighted compared to average remaining life expectancy, for one.

All minors are impaired to some degree since their brains are still developing.
