ᐅ Wind load on privacy fence (double wire mesh panel with privacy slats) mounted on L-shaped concrete blocks?

Hello everyone,
On the boundary jump to the neighbor, we had 7 meters (23 feet) of L-shaped concrete blocks (12cm (5 inches) thick) installed at a height of 150cm (59 inches) based on the recommendation of the landscaper (now divorced), with the plan to mount a privacy fence on top later.
However, I have been struggling for some time now with questions about wind load. Our setup is planned as follows:
1 post 200cm (79 inches) high and 250cm (98 inches) wide
1 post 160cm (63 inches) high and 200cm (79 inches) wide
1 post 120cm (47 inches) high and 150cm (59 inches) wide
The first post with 200cm (79 inches) height can also be fixed to the garage wall on the left, so that should not be an issue. For the remaining posts, I need to mount them directly on the L-shaped blocks. There are angled post holders available for this purpose.
Unfortunately, I can’t find any clear information about wind load requirements. Could you help me with this?
Here is a picture of the site with the fence panels roughly drawn in:
The post holders look like this:
What do you think? Should I add more posts, or is this setup sufficient?
Thanks a lot!

Beyond all the discussions about aesthetics:
The manufacturer GAH-Alberts, who offers exactly the post base intended for use here, states on their website about this model: "Recommended for fence panels up to 1200 mm (47 inches) in height." So, you probably don’t need a structural engineer to say, "This won’t work!"
Best regards,
AxelAnd they presumably base this on the wind load of a fence without the additional pressure from the gabions...

And it probably assumes the wind load of a fence without the gabion cladding... Probably, but that is not stated anywhere. And there are no further details about the plastic strips on the website either.

That was a quick turnaround on the opinion to rather say nothing when you don’t like something. Just hypocrites.

The post back then was about things that are already built, things people proudly show. This hasn’t been built yet, so it’s basically not created through hard work and effort...
And when and where I say something is none of your business, sweetheart.
PS: This gabion pressure doesn’t really make things any more pleasant. Sorry.

Axel Great, thanks for this information! I hadn’t seen it that way before. That obviously changes the project. Basically, the question then arises as to how a privacy and wind screen in these dimensions is even feasible at this point.

If this angle really doesn’t hold, which I find hard to believe, then you should create a foundation for each post behind the L-shaped bricks. In the worst case, leave 1-2 rows free so the wall is less vulnerable. There is a roughly 1.5 meter (5 feet) deep drop behind the L-shaped bricks and a neighbor.
On my side, unfortunately, I cannot pour any concrete because of the paving stones.
