You're right, it is not really a solution specifically to this problem, 'alternative' would have been better a better choice of words. Certainly I think it would be a good thing if people had the option of dying, even if they also had the option of going to a good care home - if only on the basis that dementia in and of itself may not be something an individual wants to experience even in the case where they are receiving good care.

We can think of care homes as like suppliers in a captive market, and we are the consumers - but it is even worse that a captive market in the sense that at least in a captive market you have the option not to buy, whereas we will be forced to. The existence of assisted dying as an option may even economically incentivize the care industry to improve.
