This is the heady mythology of those who said 'Crypto would create XYZ for those who cannot'.
Except it's been 10 years of Crypto popularity and they have no material function, are a huge drain of energy and human intellectual capital.
Contracts are subject to legal oversight of a Judicial system, the credibility of which is require of a system to function.
Digitization of a 'contract' really doesn't make sense so much at all in terms of it's 'legality'. The algorithm whether it's in regular code or Ehterium makes no difference.
If someone really wanted to 'help those without legal recourse' they'd just use a foreign legal system for transaction record. So, contracts between 2 people in Haiti could be designated under 'Canadian Law'.
But even that would be besides the point: It's not the 'legal system' that makes things work, it's the integrity of the system overall, maintained by a 'legal system'. Canada isn't rich because it has a 'legal system' - that's just one component. It's rich because people and groups act with integrity. The 'law' is involved very rarely.
There's no technical utopia that will replace 'integrity'. Or frankly 'values'.
Ehterium is a neat experiment, that's all it is for now.
