Note in Barrett’s Irrational Man, he did point out and highlight the evil hole that humans are facing or in. He ultimately warned readers to get out of that evil hole or ensure one do not fall into it. Barrett did suggest solutions [only generally] but ‘you’ choose to be stuck in that evil hole and continue to dig deeper to trap others to fall into it and live a life of psychological sufferings - that’s an evil intent and act.
I am well versed with Buddha’s [& others’] solutions to the problem and management of sufferings thus can easily deflect your attempts. Initially I thought you were asking for suggestions to help you to get out of that evil hole but subsequently you had revealed your hidden evil intention of trapping people into your “venus fly trap.”
Btw, I have told you earlier, you are borrowing the term ‘dasein’* without reasonably understanding what it is supposed to represent in its full range. Even if you want to use it for your own purpose you should have understood it reasonably [not necessary agree] before you deviate from it for your own use.
*By now I have spent lots of time and still reading B&T so I am reasonable [not fully yet] familiar with the concept of Dasein.
Here is one clue from B&T
Again, this expression [care] is to be understood as an ontological structure concept (compare chapter 6 of this division).
The expression [care] has nothing to do with “distress,” “melancholy,” or “the cares of life” which can be found ontically in every Da-sein. These -like their opposites, “carefreeness” and “gaiety”- are ontically possible only because Da-sein, ontologically understood, is care.
B&T pg 57 - Joan Stambaugh translationThis being fills in the significance of the term care, which is used in a purely ontological and existential way.
Any ontically intended tendency of being, such as worry or carefreeness, is ruled out.
B&T pg 192
Those ‘rival goods’ that you mentioned are problems of the ontic average everydayness - i.e. ruled out for serious considerations. But what is most critical for the Dasein in B&T [including existentialism in general] is not the ontic-existentiell but rather the ontological existential structures and processes of Dasein. It is from these ontological roots that humans can find solutions to problems and realize human-based possibilities optimally.
I anticipate you will send the above to the ‘Recycle Bin’ as ‘intellectual contraptions’ I don’t give a damm on your intention.
