Never discount the price of your freedom and flexibility, especially at this stage in your life.
I'm not sure which direction you mean this. I think I read it, on its face, as "don't take on something like this because it'll impact your freedom and flexibility when you're young," but I'd argue for the opposite: You have freedom and flexibility NOW, and you may not later, so now is the time to use those things as an asset and take advantage of them to try out opportunities like this.
E.g. the wife and I started purchasing rentals at age 22. We had the freedom and flexibility to deal with them (showings to tenants, managing them, etc.) because we were young and had lots of energy, didn't have kids yet, etc. That let us rapidly acquire more properties, and led to an early FI.
If we were instead 15+ years older, more tired, with kids, etc. it would have been difficult to do. Still doable, of course, but harder.
Your point of the OP having freedom and flexibility now is totally true. And maybe that's not worth giving up. And it's good to think about what it will cost you in terms of that freedom and flexibility, as you point out. But I'd argue that those are things you have now that you can utilize to help rocket you to FI (trading off a little of freedom and flexibility now for a ton later... time value of freedom and flexibility). :)
