how do I point her to the right path without telling her that her plans tantamount to magical thinking?
You set your own example, and talk it about enthusiastically. That probably won't work, but it has the best chance of working while not causing a rift between you and her as she gets offended that Netflix isn't going to pay her millions.
USD60k for 2 years followed by USD30k for life without having to work for it is actually pretty good if she lives in a low cost-of-living area. Let's say she lives on 25k,
Yr1: 60k income, 25k spending, debt 40k-->5k
Yr2: 60k income, 25k spending, debt 5k -->0k, savings 0k-->25k.
Yr3 and thereafter, 30k income, 5k spending, savings 25k+5k pa.
That's not huge savings but if she's receiving some sort of disability pension from her military service then she will have zero medical costs, so her savings can be for small investments, hobbies, or travel.
But she almost certainly won't do it. People don't engage in magical thinking for just a year or two out of nowhere and then stop, it's a lifelong practice. Digging further, you'll find similar thinking throughout her life, let me guess: is she also single and dreaming of a 6'4" handsome rich charming educated man who sweeps her off her feet one day? So when I say that you should discuss your own example in a conversational way, that's not in expectation of any positive change on her part as a result, but just so you can get it out of your system.
