Seems perfectly reasonable to me.
The experience of going on a waitlist and not even knowing if you'll be approved, making backups for that eventuality... it paints a very vivid picture of someone at the end of their rope, trying to end the suffering.
Other people in the thread are implying it's a mechanism for the state to cull undesirables and that feels like conspiracy theory stuff / media spin to me. The state already has plenty of tools to kill those it disagrees with, why would the slow and messy and disorganised medical system have to be part of it?
