And to note, a driver that took the championship back for ART despite Prema dominance and have bested some good talented drivers in Vesti (2nd this year) and Lundgaard who has 1 win and two poles in a car outside of the big four teams.

I don't think more teams would necessarily lead to substantially more turnover, though. Race teams, in general as well as F1 specifically, simply aren't as interested in turning over drivers as often as they were in the past.
Everything is data-driven now rather than feel-driven - and the most effective way to get consistent data is to keep the consistency from the driver's side too.
Then there's the financial aspect of it - drivers' sponsors don't account for much of the total team income and expenditure anymore. Seeking the next sponsored driver has never been less necessary for even the smallest teams. Minardi, for example, was largely a pay driver team for most of their time in F1 - that's how they lasted as long as they did. WIth F1's enormous commercial payments now, coupled with the budget cap, teams simply don't need that money.
At the same time, drivers such as Hamilton, Alonso and Verstappen bring in huge sums of team sponsorship - teams don't want to lose that.

I hope he makes it into F1 within the next year or two. I think it will be difficult, though, with so many talents also waiting for an opportunity: Drugovich, Bearman, Vesti, Iwasa, Martins, Doohan, Maloney, Hauger, Hadjar, Maini. There are so many great talents just outside F1 at the moment and for sure I am naming only some of the them. It's unfathomable, really, to think that 2024 is going to be the 2nd season that Drugovich doesn't get a seat in F1. We need developing talent like that in F1. Another 3 F1 teams would help!

I don't see how you can think Pourchaire is a "terrible" champion. He's F3 vice-champion, the youngest winner in F2 history, finished 5th in his first season, was 2nd last season, and won the title by consistently racking up points across the season. Sure, he's probably not a generational talent like Hamilton or Verstappen, but I think any team who in need of someone who is incredibly consistent should perhaps take note of him…

For those who complain about this track - watch this F2 race. The vast majority of the problems with F1 tracks are the F1 cars which 'compete' on them, and not the tracks themselves.
Even Monaco had a great race a couple of years ago - with FE cars…
