Is there a way for the bitcoin protocol to prevent the way XCP is using it, without breaking anything else?
That seems like a very big potential issue if we dont get this resolved...
The miners are supposed to filter out abuses.
Human problems need human solutions.
Not sure i understand right but bitcoin core dev team dont want anyone make new layers over bitcoin blockchain?
The problem isn't new layers, it's forcing things on people against their will.
New layers can be done on an opt-in basis, without polluting the blockchain and forcing non-participants to store the data.
