You can gather plenty of useful feedback to keep your work focused and relevant on cadences other than one or two days. What kind of customer even wants to provide feedback that often? That sounds awful, not to mention being a poor user experience, where users are treated like beta testers, with half baked features constantly pushed out the door.
This also ignores the fact that there is a huge amount of important work that is effectively invisible to the end user, but is absolutely crucial. The workflow you're suggesting disincentives the team from working on those things, and may even punish them for it (as they are not shipping customer visible features).
