It says right there.
“After the term, which is usually xy years, expires, ground lease holders at cyz generally have a preferential right to contract renewal. If the property owners let the contract expire, they receive compensation from cyz of at least two-thirds of the market value. If the house is resold, the former ground lease holders receive the full market value. Thus, cyz goes beyond the legally required minimum. Since the year blabla, it has been possible to extend ground lease contracts with a remaining term of five to 40 years according to personal wishes even prematurely.”

“From these interests results the non-terminability of the contract. Ground leases can be pledged, sold, gifted, or inherited. Termination, however, is excluded. Thus, ground lease holders are more strongly protected in their contractual rights than, for example, tenants or leaseholders.”
Exactly, it says that cyz goes beyond the legal minimum.
But if the contract expires and is not renewed,
Here the ground lease holder has a preferential right to it.
Especially with not so long remaining terms.
It can be extended prematurely here.
You write as if the legal minimum is fixed (hehe). But it remains a contract. So other minimum terms (e.g. 140 years – have seen that before), other compensation amounts (90%?), and other preferential rights for the ground lease holder can also be agreed upon...
I am a normal owner, but I also think that there are many prejudices and misunderstandings regarding ground lease. Sure, it leads to an average lower sale price, but I think if you really want to build and cannot get anything else, it is definitely a good option.
In these times, it can also be possible to have the contract adjusted in your favor.
