It's actually abnormal to actively throw away things. It's not how the brain works. Do you actively try to "forget" things? Very rarely.

We only need to throw away physical objects due to space constraints and rearrangement/search cost. Mental and virtual objects can decay away and there is no rearrangement cost when they are already organized by relevance.

My brain is constantly forgetting things. How many steps did it take you to go from your bed to your desk? What was the color of the car you last saw driving down the street? How many times have you blinked this last hour? What did you have for lunch on March 23rd? Its constantly filtering out things it doesn't think are interesting or important to me anymore, and it disappears from my consciousness.

That's exactly my point, it happens automatically by relevance ("how many times did it get recently refreshed"). It's not you going in to actively close out memory "tabs". All your "tabs" are open.

There’s literally a movement of affluent people to move into tiny houses. It may seem strange to some but maybe what’s abnormal is all this want for more more more is just marketing and one has to admit that they’ve fallen prey to it. I don’t like stuff and I loathe acquiring things. Getting rid of a car, for example changed my life for the better. Needing one in the future leads me anxious, no matter how much money car manufacturers spend to tell me I need to do just that to fit in with their status quo.

Acquiring fewer things is not mutually exclusive with not discarding things. They may even be positively correlated.

It actually does...which is how we are able to specialize our knowledge

This is the same for throwing away tabs. If I'm not using a tab anymore, I want it out of the way so I can more easily find the tabs I do use.
