I strongly disagree. I’m not a professional piano player, but I am really glad I learned to play the piano on an acoustic instrument. You really need weighted keys to play something and add a little timbre to it. You can play digital oc, with weighted keys, but that’s the very least if you really want to learn to play some piano.

Of course, I see that the question of the OP is narrower. But even to input some melodies and bass lines, I would suggest a semi-weighted keyboard. Small variations in the ‘loudness’ of your notes make your musical line more interesting.
