6If someone has physical access to PC, in principle they have access to everything. However, you can encrypt your hard drive so that one cannot easily access the data using a live USB – Archisman Panigrahi Jul 23 '23 at 13:48

This is a standards decision to enable users to replace an unwanted OS with another OS (rather than have it be return to factory)
Some non-standard machines provide features around this (such as drive encryption done at hardware level; or password must be entered before box will boot etc) but those features are often only available only on enterprise geared hardware (not cheaper consumer grade) and users don't like the hassle of entering the extra password/finger-swipe (or two) every boot/reboot thus leave them disabled.
Software encryption is the easy fix (by design!), with OSes like Ubuntu offering encryption.
