Ignorance is bliss.  :-)  Or some phrase involving "head in the sand."  :-)  Ignoring climate change doesn't make it not real.  :-)

Because of not using any spf/dkim/dmarc, the mail you send is more likely to land in other peoples' spam folders, so you don't reach them and you'll rarely ever know. Also, when some spammer wants to spam your friends, they forge messages from you, and your friends are more likely to receive it, and fall for whatever the phishing bait is.
