One issue with your argument here is that marijuana doesn't really have the same system for reporting side effects as drugs that are available through legal means (e.g. Tylenol/acetaminophen). Generally, legal drugs like Tylenol are bound to have a wider variety of side effects reported than many illicit drugs, simply because the monitoring exists.
Given that Tylenol is probably used by a much higher percentage of the U.S. population than marijuana (just a guess), a wider variety of side effects will probably be seen (and, therefore, reported). Not to mention that the legal, social, etc. repercussions that may accompany admitting to marijuana use may cause under-reporting of marijuana use, and therefore marijuana-related side effects.
The important part is to take a look at how commonly reported those side effects are; I'm fairly sure that most of those side effects that you listed above are fairly rare, and don't occur quite often - many usually accompanying overdose, or people with concomitant conditions such as liver disease, etc.
This is not all to say that marijuana may not be more safe than Tylenol (which is possible), it's just that I think that it's very difficult to compare the two drugs in this sense.
Sorry to continue the derail.
