I remember using furnaces minecarts sometime between Alpha v1.2.2 and Beta 1.5. But even around that era you were better off using the minecart booster glitch, though not sure when that was patched.
Teleportation is also one of the options, so that solves the getting stuck somewhere problem. My concern is what immortality is like without also getting invulnerability...

Don't forget you'll also go blind if you don't pay the subscription fees (but don't worry, there's an ad supported plan if you can't afford Eyesight Premium).
Oh hey, I know that game.
