Leaving this out might make your argument stronger. At least in Europe, there is no shortage of elder people that can be cared for. Most of these elder care homes have long waiting lists, and normal doctors have waiting lists as well. I think it would be more fair to say that it is an incredibly difficult decision to make as an 'outsider', and combined with how the law works with respect to death and liability, procedures and strictness with regards to euthanasia are not that strange.
