This isn't unlike other professions, but you would lose self-taught developers who don't have the time/money to afford the credential. That is currently something special about development compared to many other professions.
This assuming you prevent people who can't do something like fizzbuzz from graduating with a CS degree.
Maybe but its not the purpose to select people with families or commitment. You choose to have families or commitment, you have to deal with the trade off.

Its always be an arm race. Why to expect otherwise ?
The people who do the hiring get to the decide what the metrics is and what they considered good/qualified.
Yes, that what said, but I doubt according to the people who do the hiring.
It doesn't matter if you think you are right candidate according to you or other people. Ultimately its the people who going to hire you who is going to judge you according to his/her subjective criteria.
Hiring is still an on-going debate. Google SVP of People Ops Laszlo Bock has admitted previously that internal studies revealed that the interviewing practices at the time didn't really correlate to employee success:

We're having a debate here. You can claim the current practices are best, that's fine. But you can't just state it and take it for granted without providing evidence.
> Four meticulously orchestrated Google interviews could identify successful hires with 86 percent confidence, and nobody at the company—no matter how long they had been at the company or how many candidates they had interviewed—could do any better than the aggregated wisdom of four interviewers.
So it isn't that interviews have zero correlation, it is that they fond no case of a single interviewer being better than the aggregate of four algorithm interviews. And as you see, four algorithm interviews combined have a very high success rate.

Families are kind of important. They're usually a large part of the reason people have a job to begin with. To callously disregard the impact of a system on families is exceptionally appalling. You should not do that.
Not to mention such interview styles can be gamed. Suppose a Flatiron bootcamp for DS&A questions becomes big in response. What then? An arms race for more and more difficult weeder questions?
Such questions aren’t necessarily bad, but focusing on them to the exclusion of all other skills is becoming an anti-pattern.
