This is the point that Richard Stallman tried to hit over 2 decades ago with Right To Read (https://www.gnu.org/philosophy/right-to-read.en.html ) and got close but not quite --- yes, source code is valuable, but even without source code you should still have the "right to read" what your own computer executes, as otherwise it is not truly yours.

In fact I'd go as far as arguing that true software freedom isn't about availability of source code, but what you are legally permitted to even without.
