I think to be realistic, if the option to skip the spins, but still get cards, was availible, no one would actually do the spins. They'd just get their free cards (if any) and move on thereby making the spins totally obsolete. Personally, I find the spins entertaining. I like getting the first two quick spins then hanging on the edge just a little for the third to see if I won. I also guess it was designed that way as well.
I look at it like this. You have the power to click spin or not. If you don't want to spin, move on and click done. If you want to see if you can increase your electrum amount a little or get a free card, spin away. If you accidently misclick out of the screen, it's only you that is at fault. The only option I find viable is the "set settings to no spin" which would mean you go right to the main interface (or something to that end) after each game and therefore forfeit your spins and potential extra earnings.
Spins are a nice, little added bit of flavor and I would like to see them stick around.
