Lots of programmers use DSA knowledge on a daily basis - and if you aren't you're probably writing bad code. I see a lot of O(n^2) code or worse making apps slow for no reason. Pretty basic stuff that most people don't understand despite taking a whole class on it.
Sure I learned lots of stuff I've never used. Like relational algebra. But I also learned lots of stuff I use a lot, and it's unlikely I'd have studied most of that stuff on my own. During my degree I also had time and opportunity to pursue lots of other topics outside the mandated course material, you're not limited to what they force you to learn.
So sure if you have the motivation, discipline and resourcefulness to learn all that stuff on your own go right ahead. Most people aren't even close. Most people are much better off with a degree.

In my experience those that lack these do not have chance in tech in the first place, so save yourself lot of debt.

I don't think one can seriously argue that. This as much a meme as anything. I know it's popular to rag on devs writing inefficient software, but there's plenty of apps with functions where a user couldn't possibly notice the difference between O(n^2) and O(1). You wouldn't take the time to make everything O(1) for no speedup because someone told you that's what good code is, that's just wasting dev time.
In fact, one of the first things you learn is that O(1) can be slower. Constant time is not good if the constant is big and n is small.
