Should I? Should I Not?

The University of Rochester has just revived the PhD-MBA program. It is obviously a very attractive program. I was one of the people who rushed to the info session and seriously thinking about investing two more years of my depleting youth to hopefully obtain a passport to a "good life" eventually. Why am not enrolled yet? Here are the risks:
i) 6+2=8 years --> by graduation, I'll be a 30 odd lonely old lady with bunch of titles but ZERO work experience. People have been warning me on that.
ii) MBA tuition is not covered! Okay, they give fellowships/scholarships up to 20%. But hold on! Hear me out! I have not paid a cent for my education in my whole life, yet! Primary (elementary) school was basically free, so was high school, then came college, where I was holding a scholarship so good that I even get monthly stipend, and now grad school. So tell me! WHO pays for school?
iii) GMAT... oh no... not again! first SAT, then GRE... that's quite enough.
iV) Negative response from seniors, mentors, doctors (who are pipetting experts, not those who prescribe drugs), post docs, etc. Oh, I missed out somebody else--a manager at a biotech firm.

So what now???
