Could you explain how this rant or my job helps the amount of RAM on my phone or Raspberry Pi? Have you also ever considered that not everyone is from a first world country, able to afford the latest and greatest device with crazy amounts of RAM?
What you say is true for x86-64 desktops and servers in the first world. For everyone else, amount of RAM matters. And its you with the ostrich politics who has to stop. A quick glance at [1] suggests that, yes, you can run FreeBSD ZFS (OP was on about FreeNAS) but not without hassle.
