Which adds complexity. The CL model works as it's requirements are so simple, two humans that:
- Can communicate in the same language
- Can use a web browser
- Are able to make transactions of some kind (cash, check, Square, barter, CL doesn't care about the specifics)
Which makes their available market a rather large majority of the entire population of the Internet. Each extra restriction or requirement makes it less likely a given person will get involved.
Be very careful about "innovating" away simplicity.
