There is no such thing as “real security”, only varying degrees of protection from a specific threat model. You’ve clearly gained a lot of confidence thinking about this specific threat model while neglecting a more general and useful way to engage in discussion about threat models.

Among other things, you don’t write all the software that goes on your computer, let alone build the hardware yourself, so you’re not “really” secure at all. And because you do claim “real security”, I can’t square your statements with any threat model I can imagine.
