There is no ability to not comply. Seizure of assets is handled with financial institutions complying, and with the police backing up court seizures for physical assets.
No one is going to assault a cop, or have their bank shut down due to non compliance.
Where I am, what often happens is the damaged party has papers showing debt owed. It then becomes a colllection issue, sometimes, in some jurisdictions court takes an active role, in others, you have to do the work yourself.
Eg, you have to find their bank, hire a sheriff(the seizure kind), and go get what is now "your stuff".
If there was then a lot of America would become slaves by not paying their debts. There may be contempt here though if Elon does something to really piss off the courts.
What I mean is, the remedy for non-compliance with contracts, is fiscal, seizure, penalties of thus nature.
The goal of civil court is not the state punishing, but instead, laying out compensation, for damages, to the harmed.
There is no contempt of court for not paying these damages.
