Creative Director is just a title. You can start freelancing tomorrow and call yourself a Creative Director.
Also check out MicroJS, similar to unheap but for really small plugins and libraries.
What were you CD of at 25?
My tip is to start at a startup. As a startup grows, it'll be easier for you to climb the ladder.
I company called MakeSpace. I was hired on as a CD but the above comment has validity to it as well.
How many designers were at the company when you started?
Your article has valid points - there are some misled kids out there who think that chasing a role such as CD or AD is synonymous with being successful or even prestigious, and you are right - there are a lot of warnings to come with the chase, but I don't necessarily agree that any "quitting" is necessary and it's not as ominous as you're trying to make it sound.
Like you said, anyone who hires a 25yo CD probably either doesn't know what they're doing, or has a different view of what a CD is than what it's been institutionally - the smaller the company, the bigger the title. In that respect, I think broader titles like CD are less meaningful by themselves without the context of the organisation it's at, especially in today's warped tech / product industry framework where seniority and heirarchy aren't as a big of a thing.
Creative Directors (in the general sense) aren't necessarily hired because of their own skillset or ability. For larger agencies, it's often a lot to do with practical experience of leading a large team of creatives and being able to pragmatically impart whatever they've learnt over their XX years of making things while doing so. (Not to mention that it's often someone a bit more mature who can sell stuff in to clients).
Titles themselves are meaningless, and suggesting that someone do or do not chase title XYZ is almost a bit redundant given that there are so many different points on the spectrum nowadays, and CD's now have drastically different remits and requirements between companys.
I would say: don't necessarily chase or avoid a title. This is mostly common sense, but find out what you have a competitive advantage in, or what marketable skills you have, and then either find a role which suits that or find a small team somewhere which will allow you to shape your own role a little bit - a good option (if you can find the opportunity) is to do what Bruce said above.
Don't get me wrong, I agree with a lot of what you said, but it's mostly anecdotal and may not apply to a lot of people as well, given your role as a CD when you were 25 was probably pretty different and carried different expectations and responsibilities to a lot of other people's experiences as CD.
