Because if someone spoofs an email coming from your domain DMARC tells the receiver what to do with the spoofed email.

Google, Microsoft, Amazon and others send me summary reports of people spoofing my domains. I have dmarc set for them to accept the email, mark it spam (presumably) and send me a report. I really should and can tell them to reject the spam completely - another setting in dmarc but haven't yet out of laziness basically.
