Ozempic is but one of the available insulin's. Now I get that Ozempic is the best and most comfortable, but when push comes to shove, truth is, even an insulin from 50 years ago will do. Some of those cost A LOT less and will definitely work.
And yes, it sucks that the most comfortable one is more expensive. But ...
Ah small correction here: Ozempic isn't insulin -- it's a GLP1 Receptor Agonist[0]. While the companies that make these kinds of drugs do make Insulin (for example IIRC that's now Novo Nordisk got it's start), that's not what the drugs actually are.
