There's no guarantee you'll get what you want in _any_ amount of time. You absolutely need to timebox, everything & anything, to make sure projects aren't going off the rails and ending up in the trash. This applies even to personal/solo work too. You can keep working on anything forever, it's much better to force a stopping point, get feedback (or ship it) and decide if it's worth continuing or not. The mechanism at work here is forcing people to prioritize. If you're very good at prioritizing then a timebox maybe doesn't make sense, but even then, it may be hard to resist continuing to work on something to a higher degree of quality than is needed without a timebox.
