Sounds like a great way to have larger competitors with more capital bid for your site to take down your domain that your users were using. Rather than Land Value Tax a better analogy might be a Vacant Property Tax which only targets squatting.
The problem with that is the squatters would just turn it into a low quality blog or something along those lines.
