“Find my” app in iOS 13 lets you easily erase, lock, or otherwise terrorize any family members device on your family share

I was exploring the new “Find my” app with iOS 13.1 and I realized that under the Devices tab you can see any and all devices that are part of your collective family share (brothers, sisters, kids, spouses, pets…).
I thought “surely apple would require me to enter my wife’s iCloud password before allowing me to lock or erase her phone, right?!” Nope.
As far as I have found, there is no way to disable this or opt out of allowing your kids the unrestricted ability to erase your computer, phone, watch without turning off family sharing all together. Even my family members in which I have disabled location sharing, I still have access to erase their device without their iCloud password. Am I the only one that thinks this is a security issue?
If someone knows how to disable this without turning off family sharing, please let me know.
