With monero the whole blockchain needs to be used to find your transactions as they can be in a random chose address on the blockchain. 

So I don't think that I can prune anything because I would litterally prune one of the essential privacy features of monero. But I can be wrong so call me out if this is the case. 

 Kind of true. You can't prune to the same extent as other blockchains, but you *can* run a pruned node a fraction of the size of a full node. I've heard some say it is technically closer to "sharding" not pruning.
