This requires legislation, and a court system that upholds the law.
In the US, the courts just decided there's no right to privacy (despite what the 4th amendment says) as part of rolling back Roe v. Wade.
So, the path forward is to vote in legislators that respect basic human rights, followed by court packing (or just impeaching the judges that have been publicly accepting bribes and failing to recuse themselves on cases where they have a clear conflict of interest).
Since the above is supported by way more than 50% of the US population, the main obstacles are gerrymandering and ending the currently common practice of appointing blatently corrupt judges to state supreme courts (and also restoring recently stripped powers to state governors, since they're elected via simple majority).
