Concerns of an Android convert - Part 2

One thing I do not understand is, why do we have to unlock our phones every time we use assistant?

Now, before writing this I did take a look at settings and found:

google → search → google assistant settings → phone (under devices) → unlock with voice match

but even enabling that did not solve my problem (maybe due to a software update bug?). This problem being that you have to unlock your phone anytime you use assistant, even for minuscule things like setting a timer or checking the weather.

One feature I was under the impression Google had, but apparently they do not, is a “Ok google, find my phone” feature. I understand you have a “find device” app but what I am suggesting is a command. This would be, for example, when you placed your phone in your room but can’t find it. All you would have to do is say “Ok Google, find my phone” and it would emit a sound of some sort so you can locate it. But let’s say Google already had this feature, how exactly do they expect me to unlock my phone when using a command like this? THIS IS THE WHOLE POINT OF THE COMMAND, that I do not know where my phone is so how am I expected to unlock it?

Similar situations, including this one, could be avoided if you had a Google Home device. Here, simply saying "Ok Google ___" would automatically complete the command since it was done through Google Home rather than your phone. What if you did not have a Home device? What if you're cooking, your hands are dirty, and you need to set a timer? Or you need to reply to a text? Commands like these become challenging even though they are simple. Looking back at my first post, it all comes down to added expense. First it was headphones, now its Google Home. I was lucky enough to get a Home device through a promotion Google had when you purchased a Pixel 2, but what about other users? This added expense is completely unnecessary.
