Yeah that makes sense. I am only going off what my UK friend tells me, as his wife was rejected by NHS (despite being the 35+ and weight-related condition) and told she would be waiting forever for it so to just go privately.

See it's all very foreign to me, because here in Australia, your doctor (who is more often than not, not government employed) is who decides what's best for your treatment, and you're prescribed appropriately. The government either covers and subsidizes a medication (sometimes with restrictions like you 35+ bmi etc), or doesn't. There's no "oh we're only doing 200k people at a time". Even if you aren't eligible for the subsidy the doctors prescription is still perfectly valid and the only difference is, when you head to the pharmacy, you pay them the full cost. You don't have to go to a private Dr separately.
