The device doesn't even have the same specs, the $4000 is for a MacBook with 2 TB SSD and 64 GB of RAM yours has a 1 TB SSD and 32 GB of RAM that's half.
Other than that yes MacBooks are expensive. But so are HP EliteBooks or Lenovo ThinkPads.
There is a Lenovo storefront called "perkopolis" to which you can find an entry key fairly easily that has deeply discounted thinkpads. So for example a 5800HS + GTX3060 + 16GB RAM + 512GB SSD laptop is going to run you around 1200$ there vs 2000$ without a discount.
