I guess don't do it then, but it just seems like a suggestion for people to try, to me. That makes it more like "a fun new activity that you truly enjoy doing every day" than social pressure.

It also is another use case for those of us still in the habit of spending fiat. 

However, you're right that more (less gimmicky) use cases will have more impact.

Spending Bitcoin - A Weekend Discussion

imagine you were trying to change your habits in another domain, let’s say fitness.

coming up with a fun new activity that you truly enjoy doing every day will be a far more effective method of improving your fitness than any form of social pressure.

i see the spend and replace movement as social pressure, while i think we should be focused on finding new use cases that people naturally want to spend their bitcoin on.
