Real World Assets and "supply chain" coins are one of the oldest scams out there.
You can not represent a real world asset digitally...
or rather you can't SECURE a real world asset digitally.
A cop is not going to arrest someone because you downloaded their JPEG.
A cop is not going to evict someone because you claim to own the private key to the house.
The entire legal system would have to completely disappear and be reinvented for RWA to be a real thing.

I feel especially vindicated on this issue because I introduced a high powered lead dev from a big entertainment company in LA to Ethereum in 2018/2019. They asked me about real world assets and supply chain and I told her absolutely not don't even try; it won't work... then years later she got back to me and was like yep you were right it didn't work for the exact reasons you said... lol.
