...and to prove your point...MLS clubs have been steadily turning their focus in the transfer market towards Latin America over a number of years. It's not really just Argentina, there are young guys coming from places like Uruguay, Ecuador, and Venezuela as well. Inter Miami just signed Venezuela's U20 captain today.
There's a belief that you get better value there than you do shopping in Europe, and many of the players signed are young enough to potentially be attractive transfer targets for European and Mexican clubs. In some cases, it seems like MLS clubs are overpaying a bit, but I think they're learning.
All this stuff is why it's painfully eye-rolling when people call MLS a "retirement league".

But still - MLS is a little too tough to be a rocking-chair league now.
