The will of people isn't always what they really need, and senders are only one side in an e-mail transaction :-) One problem with SPF/DKIM/DMARC is that due to non-malicious manipulation of messages (for example forwarding etc.) messages may look invalid at the receiving site. Forwarding is most often used by recipients to achieve their preferred way of handling mail, so rejecting mails that they want to receive would mean you ignore their wishes as recipients in favor of the wishes of the senders who often don't take these machanisms into account. In the e-mail world, the will of recipients is ignored often enough (spam spam spam, lovely spam), now ignoring it again in the name of respecting the will of the sender wouldn't really be helping recipients trust the medium.
