You can travel by hitchhiking (free), walking (free), cycling (one bike costs) or even by volunteering on a ship (you might even earn money). You can sleep in a tent or couchsurfing or on said ship.
Everybody immediately goes to restaurants, transcontinental flights and hotels, of course you need money for that, but that’s exactly not the point.
ITT: but first class tickets and 5 star hotels cost money!!!

Economy tickets and hostels also cost money.
Walking, biking and couchsurfing is free. In most countries camping is free too.
Couchsurfing is free? No, it comes with the cost of having people who trust you enough to let you in their houses.
Biking is not free.
