For most people, I think the "floppy disk" security model is usually 
appropriate - you can take your data out of your computer and put it in your 
pocket, where nobody can read it without physically stealing it from you first. 
 Unfortunately it's hard to apply using modern technology and paradigms, which 
try to move your data out of your house entirely, for "convenience" (and to 
trawl through it for great profitssss).

This is also, for example, why IoT devices and voting machines built using 
modern technology are perpetually insecure and unsecurable.

Currently, the easiest way to build a machine that's *truly* secure is to take 
something like a 6502 (which is still being manufactured by WDC) and associated 
74AHC-series logic chips, SRAMs and EEPROMs, a 4-layer PCBs, all of which are 
built on crude enough technology to be physically examined for backdoor devices 
in an airport-grade X-ray machine if necessary.  Then write the necessary 
software in assembly, which can be translated to machine code (or at least 
verified) by hand if you're truly paranoid, and toggle it in byte by byte on 
the front panel.

Good luck getting a web browser running on one of those, though.
