First of all, a "cryptographer" is an academic who invents cryptographic algorithms and publishes papers such as
this guy on who's work Darkoin is based, not a cryptocurrency linux geek fanboy of one coin or another. As far as "laughing stocks" go I suspect your referring to the latter.
The -wizards crowd are Bitcoin core developers (all of them, including Gavin Andresen, Wladimir van der Laan, and Gregory Maxwell) and cryptocurrency academia (researchers, professors, etc.)
If you want to know how cryptographers really feel then a good starting point is
the first answer on this StackExchange post, which was originally on crypto.stackexchange.com and then eventually migrated to bitcoin.stackexchange.com. There's enough cryptographic research meat in there to justify the read.
Secondly, someday the market may buy some of these hypothetical vulnerabilities that you've posed. But it's looking less likely by the month because, luckily for it, the market is in a position to "have its cake and eat it" and as such basically regards Monero as a backup policy for DRK. There just isn't enough mileage in any of your criticisms to justify a huge disinvestment and recapitalisation in another crypto currency asset.
I'm not suggesting anyone invest in Monero unless they are absolutely fine with holding for quite a while, maybe even several years, and they understand that it is an experiment, one with no guarantee of success. If there is a huge recapitalisation from Darkcoin to Monero it certainly won't be because I wrote an eloquent post on Bitcointalk:-P
