Firstly, pasteurisation is most definitely a process.
Secondly, it’s very unlikely you are buying milk which has only been pasteurised, it has very likely at least also been homogenised, after being mixed from various different sources in order to produce a mill standardised fat & milk solids. The vast majority of the time rather than just being blended, it has been centrifugally separated into fractions that are then recombined in order to create a standard product.
None of this is really bad, btw, but it is 100% processing.
Well you can run doom on Linux, so obviously yeah
