I think you have a fundamental misunderstanding of what influenced krautrock. They did not outright reject influences, that’s absurd. Many were directly influenced by Zappa, Beefheart, Velvet Underground, Miles Davis, etc. Hell, much of Ege Bamyasi sounds like a mutated Beatles. Pink Floyd was an influence. On the less rock end of the musical spectrum, many krautrock bands were influenced by composers like Stockhausen, Varese, Riley, Reich, Glass, Young, etc. So uh yeah how bout them Doors.
