I could do that but I don't want to reacquire the games again if I ever desire to play them again in the future.I have a 32GB that has lasted me ever since I put CFW on my N3DSXL (Now have A9LH) I just delete games I don't play since I don't really play me 3DS all that often anymore.
I can see why people are for digital ownership but I'd sooner choke on my own vomit than be expected to pay full price for these games.
