I think there are a few situations where this is reasonable.

You have a stream of income, even a small one, like disability, retirement, investment returns, or location independent work.
Or
You don't have kids and are able to live and little and weekend
Or
You're independently wealthy.

In other words, I think you can give up a lot of plans, but you have to at least have a plan for money.

Very true... Money rules all

I wish it wasn't so, but those kids keep eating all my food!
