Why should I link to other websites with a Do Follow Link

Why should i link to other websites with a do follow link when I can use no-follow option (or other options such as sponsored) and not dilute my authority? (I know that technically a do follow link doesn’t exist but for the sake of this conversation, a do follow can be considered anything that shares authority to the linking website)

Is there any incentive for me to share authority to other sites (other than for money)?
