Put them in a socket?

What *kind* of socket? Even if you do a CPU socket thing ($$$ and adds thickness) just making space for the thing plus the interconnect significantly increases total trace length. There's a reason why the M1 has ~0mm between the SoC die and the memory dies.

Mobile aka phones is fine. Laptops, it is unacceptable

Why? Laptops have batteries same as phones, why would you not want them to last longer?

Repairability is not an issue here, I think. Getting rid of the slots makes us more dependent to specific companies and creates monopolies. Instead, we need replacable everything till we totally switch to riscv or such an alternative.

RISC-V has nothing to do with any of this. The only difference between RISC-V and ARM is if you want to build an ARM CPU you get to pay ARM, and you don't have to pay anyone for RISC-V. Nothing to do with RAM, repairability, modularity, openness, etc.

I still think we should have *good* modular laptops, even at the cost of power efficiency or performance, and even if we can only replace RAM and storage, it's still something many people, including myself, really want for various reasons (repairability, upgradeability etc)

Storage is much more important than RAM in my opinion. I almost never upgrade RAM, but I've upgraded storage on pretty much every laptop I've owned.
