I still say yes.
I don’t approve of the word “blindly” (two posts) being used here. It is a manipulative word used with the intention of disparaging before the discussion even begins.
Besides, the OP didn’t ask if it’s legitimate to follow all psakim of the Ya’avetz, just “A” psak. And even if he did mean all, I can say, “I am a descendant of The Shach, of the Ya’avetz, of the Gaon, of the Chasam Sofer, of Rav Shlomo Kluger, just pick one,and it is our family tradition to do this, this, this and this. And that is perfectly ok.
Look at the Teimanim (Rambam). Look at the Prushim from Sha’arei Chessed (the Gaon). Look at the Satmar (The rebbe died when? 32 years ago). Look at the Bambergers and Breuers. The examples are many more than I can list. There is no such a thing as a consensus that is binding. Not in halachah, nor in hashkafah.
Rav Ya’akov Emden was one of many giants who are worthy of being followed. It’s ok.
