I did have sufficient funds but drawing a loan is more capital efficient. I responded to another comment in this post explaining why.

Also, this was not my scenario but a common view: it can make sense to draw a loan so that you're not liquidating long-term holdings. Imagine I hold $100k in bitcoin and need to pay off $15k in student debt. If I sell my BTC, I'll incur capital gains tax and also have a smaller long-term holding. Alternatively, I can borrow $15k against the BTC, pay no tax, and keep my BTC position in full. There are various ways to then generate interest on the BTC and pay back the borrowed funds.

Some platforms offering 0% loans include Liquity and Alchemix.
