However, your option list has enough glaring omissions that it seems as much of a hit list as the article:
1. Eliminating disposable packaging is a worthy goal but reducing the harm of individual disposable packaging materials is always going to be part of the solution in the medium term, and there is PLENTY of innovation in this area. Not least in less environmentally intensive disposable yoghurt containers.
2. You keep repeating "recyclable" but never "reusable". e.g. ceramic is also used for yoghurt containers where I live, as well as glass, and it's common to see both types of familiar-looking pots reused throughout households.
3. Other commenters have mentioned larger containers (which incidentally is what I do). Reusing every reusable container might become unwieldy if you're buying a few dozen single-serves per shop but if you're consuming that much yoghurt then big containers are going to be much better in many ways.
4. I haven't seen this happen with yoghurt just yet but it's extremely common to have bulk stores with refill facilities for milk, syrups, honeys, peanut butters, dry foods & washing liquids, so I see no reason this couldn't happen for yoghurt.
