What are all the types of assets?

Question

I'm fully aware of:
*commercial, medical, residential, retail real estate.
*private businesses, real estate investment trusts, stocks, mutual funds, exchange-traded funds, oil/natural gas trusts.
*corporate bonds, municipal bonds, other government bonds.
*precious stones, precious metals, other non-renewable natural resources that can be owned.
*knives, firearms, dehydrated food, water, water purifiers, other mostly-functional survival objects which could be traded after society collapses.
*knowledge of how to build, operate and repair systems, be they business or mechanical.

I'll define an asset as something that can add value to you or someone else, and can be traded for goods and/or services. I don't consider a job to be an asset, and self-employed-type skills like salesmanship are covered above under knowledge. Please don't start splitting hairs about any of the above (for instance, palladium goes under precious metals). I'm an investment fiend, and I need a new fix.

Answer 1

I think you are missing a big part of the intangible category - brand names and trademarks

These can by protected via patents and sold or leased.

Answer 2

sounds as though you've got a handle on it all, but other than naming the assets, the headings are:
general, fixed, liquid, real and others.

I can place all your assets mentioned under one or all of the aforementioned categories.

thanks for the stretch
