It should be noted that these gardens are comparatively cheap. For many there is no other feasible way to own a few 100m² of green and free sky.

I'm also not sure where they're getting the 12,000 from, since to my knowledge every "colony" manages their own waiting lists. If they're just adding the number of people on each list to arrive at the total, they're double-counting people who're not looking for a garden in a particular location and appear on multiple lists.
All in all, if you really want a garden, it's absolutely feasible with a few years of waiting. And if you just want to dream about having one, you can still put your name on the waiting list and politely decline each lot they offer.
EDIT: there's also a sharing platform for people who need help gardening and those who want to do it: https://www.datschlandia.de/ That is another way to get the benefits of a garden bypassing the waiting lists.
