If possessions and power are tossed out the window, some people might ask what's left of wealth. Increasingly, people will tell you that "time is money" and so, anything you can do to increase time you have to devote to what you prefer doing would then contribute to wealth. 

Standing back, where you create situations that have beneficial results for yourself and/or others, then this would be considered a kind of wealth creation. A benefit remains a value judgment.

If you cherish your health, then discarding or changing any habits or practices which undermine good health and well-being inversely promote a kind of intangible wealth. That is worth having.

Where you decide to buy less manufactured goods and share what you have more, this would conceivably promote more communication and stronger relationships. Take a lawn mower example. If you own one, how long do you use it in a given year as compared to how long it rests idle in the garage? If you and your neighbour shared one, you would spend less money and the machine would get more use. You wouldn't have to spend the start of a season getting it to work. You could even lend it or rent it out to other people, which would spread your wealth and joy.

Traditional wealth reminds you that many things have monetary as well as exchange value. What you have and how you choose to share can also be measurements of wealth. The usefulness of an object brings you a kind of wealth in the form of convenience and possible saved time.  Keep your mind open.  Rather than toss real objects out the window, why not discard outdated or close-minded ideas? Doing so will prepare you to embrace new kinds of wealth and prosperity.
