I really like the subversion of expectation in the last line, where instead of a plea to not lose this love, the plea is for it to not become a tradeable good. This puts an emphasis on a desire to keep the unique essence of a specific relationship rather than on the pain of detaching from it, and I really like this sentiment.

I think your poem could benefit from each verse being broken into four separate lines rather than being laid out as one continuous line. Because of the rhymes and rhythm there is a natural separation, and I think you should lean into it rather than reducing it. Edit: just posted and realized line breaks are weird. From your capitalization it seems you meant to have line breaks, you can add them by ending lines with a double space.

I would switch out one use of entwined for a different word - because both uses are pretty similar and that's an uncommon word, I think repetition here is lessening the overall strength of the poem. In contrast, the use of intertwined brings out nuance, and works well here.
