Why aren't all Google apps removeable?

[AC Question]

why dont make all google apps removable ?

Never expected to read about root on android or even explain it, root is a big step since can brick phone but it can modify almost everything, I just think on that to remove some factory apps I dont like, then why dont just make all google apps removable ? I already bought the phone, wether I use the apps or not won't change anything, just waste space and sometimes ram

pd : I am talking about google/android apps, not about brand ones
