The original Bitcoin whitepaper from Satoshi Nakamoto is available here: https://bitcoin.org/bitcoin.pdf
It is titled "Bitcoin: A Peer-to-Peer Electronic Cash System"
So, based just on the title, it's pretty clear that it's original intent was as an electronic payment method.
The first sentence of the abstract is: "A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution"
If you read the rest of the whitepaper it's pretty clear that the original intent was as a mechanism to facilitate payments and transactions.
Clearly, at least one person (the author of the whitepaper!) "desired" Bitcoin as a payment method. They desired it so much, that they went off an invented it!
If that doesn't count as a source indicating what someone "desires" then nothing does.
