On the other hand, the only moment in which you have direct control and could actually affect is the current one.
When Pinocchio made his wish, was “agency” all he wanted, or was there something more?
I have recently been envious of a neighbours bushes - they flowered uninterrupted for many months, all spring, summer and autumn. Fantastic sprays of cream and crimson blooms. Both beautiful and long-lasting, I would love to plant those over more temporally limited ones that only flower for a few days per year.
It is not the permanence that is unappealing about fake blooms, nor the brevity that makes flowers beautiful. To me anyway. Silk wallpaper with floral prints that has survived for hundreds of years in old British castles and country homes is no less beautiful for its age.
I’m not sure I see the relevance of your other points. I guess we see things very differently.
