Things like RAID can effectively cover the hardware failure side
Note that RAID only covers one specific hardware failure. To the point where IMHO, you cannot consider it a data security measure, only a data availability one.
It’s they decide to shut down or raise prices or whatever, you can reevaluate and move.
Move at how many hundred $ per TB?
except for hdds without cache
The "cache" on HDDs is extremely tiny. Maybe a few seconds worth of sequential access at max. It does not exist to cache significant amounts of data for much longer than that.
At the sizes at which bcache is used, you could permanently hold almost all of your performance-critical data on flash storage while having enough space for tonnes of performance-uncritical data; all in the same storage "package".
It might be underpowered, it might not be. Just test it out? Do you notice performance issues related to your router?
I thought about switching the router to a dedicated one without a wireless access point
Is there a reason for this? Unless it has specific issues you'd like to fix, I'd just keep using the current router and simply disable its WiFi.
Isn't that the cloud shit?
AMD platform support is coming to coreboot in the next few years, consumer platforms much later and even there I'm doubtful it'd come to your laptop in particular.
Get a Frame.work with Intel chip if you want coreboot on a modern laptop soon-ish. I know the guy working on that port ;)
WDYM by "overheat"?
Wow, stark; 1.4 Prozentpunkte hinter dem Markt.
Warum will man das?
What you're doing is perfectly fine.
It is however more of a mitigation for bad distro installers than general good practice. If the distro installers preserved /home, you could keep it all in one partition. Because such "bad" distro installers still exist, it is good practice if you know that you might install such a distro.
If you were installing "manually" and had full control over this, I'd advocate for a single partition because it simplifies storage. Especially with the likes of btrfs you can have multiple storage locations inside one partition with decent separation between them.
User agreements aren’t really enforceable

if reddit got their way, then that means publications can no longer cite Twitter comments.
Why would publications no longer be able to execute their right of fair use?
I use multiple offline HDDs with a policy to keep n copies between them because it's by far the cheapest way to still own the data. It requires regular checks because HDDs are likely to fail after a decade or so and a bunch of HDDs are a pain to manage, so you will need tooling for this. I use git-annex for this purpose but it's not particularly user-friendly.
