Personally I think you think in term of "what if I start to work FOSS way today" instead of "what if we push all together a political reform that mandate Free Software". In the former you are wright: if you live on a single proprietary software sold as a product you easily find yourself done, in the letter you have to look back at IT history where at start, not in academia but in business software was normally open and companies are far stable and profitable than today.

In an open world you can't sell product, you sell skill, time, resources. If you try to be something like JustEat, Booking, Expedia, ... you are simply dead, but that's not a problem except at an hypothetical "model change", that's a good things for the society that prize real innovation ad work instead of marketing ad use (legitimate or abuse) of a commercial position.

It's not a matter of fundamentalism but a different social model.
