Or any other feature genuinely lacking from IPv4. Merely having unique address for every grain of sand on the planet isn't enough.

Why not, actually? I would think simple and trivially auditable HW RNG with, say, only 0.9 bits of entropy per output bit (raw! no whitening) is preferable to "perfect" but fragile algorithm.

Anything that requires the randomness in practice has enough overhead so that the 90% good entropy is not a problem. Failures caused by wrong assumptions and complications are.

And all the DDoS and crytocurrency extortions and scams should extend to meatspace too, and you would be okay with it because it's supposedly still better than what govts do?

Everyone else can get get strip mined for attention and croak, you don't care.

Such an idea might be a good startup pitch for gullible investors but won't survive clash with reality.

Good, such things could never happen in the US then./s

But seriously, can we stop such stupid soundbites?

BTW most of zram tutorials get it wrong, you are supposed to manually mark idle pages and initiate writeback by periodically writing to /sys/block/zramX/idle and /sys/block/zramX/writeback . Otherwise zram will never ever write anything to backing device. It is documented in kernel docs, just that if you expect it to work automatically you might misread it.

And you can convert swap into such backing device, but then you don't do swapon on it (just remove it from fstab) nor it's necesary to format(mkswap) it.
