Not at all. If you talk to a few dozen people who "traveled a lot" before they turned 30 (including me, the person to whom you're replying), the single most common thread in all those stories will be how cheaply they did it.
Life on the road costs ~$500/month. Life in an apartment costs ~$2000/month. One of the simplest ways to save money when you're not working is to ditch all your possessions at home and go find a nice cheap tropical beach to park it on.
Having "retired at 30", using the author's definition and a similar methodology, you'd be surprised at how much living I did along the way and have done since.
