Hot Take
The 'Cash Envelope' Trend Is Just Adults Relearning Object Permanence
The envelope isn't the innovation. Not being able to lie to yourself is.

The cash-envelope trend gets treated like a discovery. It is not a discovery. It is a generation relearning object permanence because digital money made it possible to spend without ever confronting the spending.
A card tap doesn't feel like anything. The number updates somewhere you're not looking, and the spending becomes abstract almost immediately. An envelope emptying in your hand is the opposite of abstract. You can watch it happen. You cannot pretend it didn't.
That's the entire mechanism, and it's worth being honest about it instead of treating the envelope as a clever hack. The hack is forcing yourself to feel the transaction. Cash is just a convenient, low-tech way to do that.
If a spreadsheet made you feel the spending the same way a shrinking envelope does, the spreadsheet would work just as well. It usually doesn't, which is the actual finding here, not the envelope.

The Actual Questions
Why does cash-envelope budgeting work for some people when apps don't?
Physical cash makes the spending visible in a way a balance on a screen doesn't. Watching an envelope empty is harder to rationalize away than watching a number update.
Is this actually a new method?
No, it is decades old. What is new is a generation rediscovering it because digital money made spending too easy to not feel.
Does the envelope itself matter, or is it the visibility?
The visibility. Any system that forces you to physically confront the spending as it happens gets similar results. The envelope is just a convenient object for that.
