Sure. But decenterinf isn't about becoming selfish. It's about focus. Where and how much focus you put your energy and attention toward.
Also, like any and all movements, it's a rebalancing. It need not be forever.
It's not selfish to take care of yourself enough so that you don't fall into crisis. It's being responsible and accountable to your community. You can't take care of anyone else if you're drowning or gasping for air.
Decenter is a pause to catch your breath.
