There is a glitch that is being abused in a server for removing reinforced blocks & protected items without the consent of the owner or without the use of "Universal Owner Changer" and/or "Universal Block Remover".
SecurityCraft glitch
Consists on the use of vanilla blocks such as pistons, tnt and obsidian to remove reinforced blocks, protected chest & doors.

I personally feel unsecured with such glich and find no purpose on crafting reinforced blocks & security items.

Unfortunately, that is a Minecraft glitch (that also works for removing Bedrock or any block you wish, as you said) and thus this is most likely not fixable by us without hooking deep into Minecraft's code. Maybe there exists a mod or datapack somewhere that fixes this mechanic, but if you can't find such a tool then you probably need to wait until Mojang fixes this bug.
