The constituents of the person physically exist, the different scales are just labels to group the particles/atoms/molecules/...

Corporations on the other hand exist purely in the mind, it's not about scale. It's just a tool, a mental framework. From https://en.wikipedia.org/wiki/Juridical_person

> A juridical person is a legal person that is not a natural person but an organization recognized by law as a *fictitious* person such as a corporation, government agency, non-governmental organisation, or international organization (such as the European Union).

Also limited liability companies did not really exist until the 19th century. It's just useful abstractions above people interacting with each other. I get it's easier to live not being conscious of the bare metal, too bad people lose their humanity in the process.
