I did not downvote, but I'd like to offer my point of view.

Owning a home IS an investment. Renting is not.

I think this is a superfluous distinction. Purchasing real estate can be an investment vehicle if you aim to recoup the investment through appreciation (land speculation) or income generating usage (like rentals). It may also not be an investment if you just want to purchase a property to live in it - this is a passive asset, much like a car. You can "rent" your car (and time) to the gig economy, and car prices can rise and you can make a profit by selling one, but in a stable supply market that's not the norm so cars are generally not regarded as investments. Conversely, renting retail space for commercial usage is an obvious example of income generation on top of a rented property, so rental costs are a factor in other types of investments.

Nobody would want to own a home if they didn’t get some kind of return on investment when it came time to scale down/retire/put it in your will, etc.

Plenty of people want to own a home regardless of financial returns. Ownership has its perks, there are plenty of people willing to pay for it. It is a bit of a luxury good nowadays, but one that is very entrenched in most cultures as a symbol of "making it".
