Ok, that might be a point...you could open a second checking account with your same bank.(the chance that your # is compromised, that account wont hold your main funds this way)
Give that # to etsy, when etsy makes their deposits you then transfer it into your checking, savings what ever you need from your online account with them.
Personally, Ive used both the DC and the gift cards since they first came out. Have had no issues, and i LOVE not having to try and walk a computer illiterate buyer though paying with a CC with pp! 0o
