How important is the 5-year rule?

I work a fully remote job and love to travel while doing so, but am also interested in buying a home, partially as an investment & partially as a place to start building out some of the things that I love (I'm a homelab nerd & love tinkering and need a place to put a 3d printer / NAS / etc.)

I currently have enough money for a down payment & can afford a monthly payment. My thinking was to buy something near where my parents live, live in it for a year or two while I work on some of the aforementioned hobbies before traveling again. However, the common advice I see is to not buy something unless you intend to live there for the next 5-10 years; however, I don't intend to live in any one spot for the next 5-10 years. Is buying a home a bad idea in this context?

Thank you so much
