Geez. There's even websites.
Laissez-faire, do-it-yourself suicide has always been with us. Sad, but --- face it --- universally available.
The purpose of legalized euthanasia is to grease the skids for people who are NOT choosing suicide --- or not choosing it promptly enough to gratify the more powerful individuals and government and corporate entities in their lives.
It's really not a matter of liberty for the individual. The whole point is cost-containment for healthcare/insurance systems, and--- especially for sick babies and stressed women --- a cold-blooded, enforceable buh-bye.
...can always commit suicide.
When you're left quadriplegic after a car wreck, you can't even wipe the drool off your chin. Suicide is only easy with a functioning mind and body.
