I don't want to mine a broken coin either but the reasons you have given for stopping mining are instamining and technical issues (moneysupply and checkpoints).
A relaunch won't fix the instamining problem if you do an airdrop to the original miners because the instaminers get coins too.
Whatever issues there were with moneysupply and checkpoints seem minor, and I see no reason to think they couldn't be fixed in a future update.
It feels like you are making up really lame excuses because you were planning on instamining more coins but other miners got to it quicker than you had hoped.
I don't think the issue was actually caused by instamining. again it was because every wallet we had had a different wallet money supply output, and other information that was innacurate. We thought we had forked, one of the developers said that maybe we forgot to make the git public, when in fact we did make it public after all. there was a lot of confusion and a lot going on. Again, we're sorry. We have a lot of time in to this project (we've been working on it since july of 2015) and we need to make sure that things go right at the launch for us to bring it in to fruition. We're going to make the necessary fixes and start over.
The only problem with moneysupply was that it was reset every time the client was closed. Not a big deal you can fix it on actual chain
