Should it be illegal to horde domain names?

Do you think it should be illegal to own a domain name and not have any significant content provided by it?

Significant content could be defined as simply as an about us page or a coming soon page.

Does it make it harder to do general population business without a .com TLD?

Should there be a time limit on owning a domain name without significant content (as defined above?)

Would life be easier if domain names needed to be tied directly to a business? DBA, LLC, S-Corp, etc... ?In the USA, setting up a Doing Business As is a pretty simple thing to do requiring just an hour or 2 at a bank / city hall.
