If you remove money and religion from the world, would all its problems disappear?

In my opinion, no. The world's problems aren't inherently caused by any of these things, they are caused by people that misuse, abuse, or otherwise capitalise on an unfair advantage or opportunity.

Yes, terrible things have been done in the name of religion, but religious organisations have done good things too. Some people find a lot of comfort in religion.

Same goes for the arguments for and against capitalism. Capitalism had driven incredible advances in technology and society in general, but some people take it too far, putting profit before people and amassing obscene amounts of wealth.

I think all problems can really be traced back to human greed, whether it be for wealth, power, notoriety, or something else.

It seems people have forgotten that bartering or 'capitalism' is the *natural* way of doing business.   

Thousands of years ago, if I showed a talent for sharpening knives, it's more sensible for me to spend my days sharpening knives for the village.    Unfortunately, that would mean I couldn't tend my fields so I would need to be 'paid' in a 'currency' of things I could swap for what I needed like goats or corn or  bread.      If I was good at my 'job',  the village would be more productive so I could start to pick and choose whose knives I sharpened first - so I could 'charge' more for my skills.     I would become 'wealthy' as I have the monopoly on sharpening.

That would encourage people to set up in competition with me - the customer would choose who did his knives - my expensive skills or a cheaper, faster, lower quality competitor.     Market forces would soon find the balance.

Obviously, goats and cows are hard to carry around in my wallet so money is just the representation of those valuable things.  

So no, I don't think you can get rid of money.

Similarly, people seem to universally need hope - and as that is normally wrapped up and delivered in an organised, pre-packaged religion, I don't think you can get rid of it.

Years ago, a ruler would have an heir - and a spare.    Both heirs would want each other dead to clear their path to the throne.

The youngest would usually escape into the church to gain power against the sibling.      Both of these maximise their revenue streams - one by threatening direct horrible pain and misery if the people didn't pay their taxes while alive and the other threatening eternal horrible pain and misery if they didn't 'invest' for their afterlife.      

The little people do not ever declare war on other countries - it's always the power-mad rulers - and often 'religious' wars are just one family fighting a distant branch of their own family to regain wealth stolen by the others.
