There have been some cases where there was prosecution of doctors because of protocol violations.
But I can't recall any 'abuse' of killing of elderly people for the inheritance.
The reality is that nothing is fool-proof. In theory anything ever can be abused.
But the risk of harm vs. the risk of benefit is too great in favour of the benefit.
That's why we drive cars even though they kill 40K+ people a year in the USA.
So I don't think the theoretical risk of abuse is a good reason to not allow Euthanasia.
Edit: In The Netherlands, each case of Euthanasia / request for assisted suicide is evaluated by multiple doctors / psychiatrists. Each case has to be reported to a special Euthanasia commission that will also verify if things were done right. We don't go over it lightly.
Is anyone looking for it?

Also, political party D'66 is now pushing for the right for someone to end their life if they consider it "completed", without there being any serious suffering.
Note that not only the christian parties, but also the Socialist Party is very critical about broadening the criteria for euthanasia.
Thinking that your life is “completed” is related to suffering: if life is pointless or meaningless to you, having to go on is suffering.
This is a freedom for which many, including myself, may eventually benefit versus the alternative. I may want to make such a choice for myself (hopefully many years into the future!) rather than live in agony and I really hope the option will at least be there for me in my country.
The challenge is to have proper regulation, with the right checks and balances in place - I don't think anyone is suggesting you can just rock up to your local euthanasia corner-shop and say "can I haz dead pls?".
I don't think this is the case though, and I agree with all of your second paragraph. But I do think (and it seems that) potential to misuse a freedom is sometimes enough to restrict it, even completely.
- suffer a "serious or incurable illness" or a "chronic or incapacitating" condition that causes "intolerable suffering"
- be an adult Spanish national or a legal resident
- be "fully aware and conscious" when they make the request, which has to be submitted twice in writing, 15 days apart
As with all irreversible decisions (death) there's going to be plenty of paperwork - and rightly so.
Hence the heinous but popular crime of scamming seniors.
