I understand what you're saying but you're just drawing the line at a much higher income discrepancy. Who decideds what constitutes "a disgusting, obscene, amount of money and resources"? You? A farmer in India? A Russian oil tycoon? The poverty-line in Zimbabwe is $202-US/month, $2424.00-US anually. Does that give a Zimbabwe resident living in povery the right to help themselves to anyone's goods? Does that give them the right to help themselves to the resources of of a US citizen living in povery. After all a single-person household in the US pulls in around $11,000.00-US/year, nearly 4.5x the amount of the hypothetical Zimbabwe resident. At what point do you draw the line?
Your beggar's cup analogy isn't quite accurate either, since you, the original of the holder of the resource, is deciding to write the loss off. This is quite different than someone else deciding to make that decision on your behalf.
All of society's problems that are attributed to marijuana are really problems that stem from the laws against it.
There, fixed that for you. I'm fairly certain legalizing things like meth and cocaine wouldn't do much to aid the addicted. Just because one drug is harmless doesn't mean they all are.
Criminals are generally a symptom of larger social issues.
I don't disagree that certain criminal acts are products of desperation, for instance a thief stealing to feed himself or a young woman using fake ID to escape an abusive boyfriend, but your proposition assumes that if given the option, people will always do the legal/right thing.** This doesn't account for criminals who commit their crimes in spite of other options. The perpetrators of the giant economic con-job that ended up causing an economic melt-down were, in all likelyhood, quite capable of feeding themselves and their families without financial shennanigans. I have met individuals who financed their lifetstyles with criminal activity because, frankly, it paid better than working a legal job. Now, you could counter that this is an example of a social issue that needs addressing (wage floors, etc) but in doing so you remove some of the agency of the perpetrator, since the criminal is now only capable of taking the path of least resistance.
Again, I don't disagree that some crimes are products of social issues but saying that criminals generally commit crimes because they have no other choice is problematic at best.
**Yes, "right" and "legal" are not always equivalent and in several instances can be in direct conflict with one another but that's outside the parameters of our discussion at the moment.
