More subtle; if you are willing to pay $1,000 for the renewal, then a company can buy it from you for $11,000. If you only make $100/year on it, then a company can buy it from you for $1,100, which is more than you would make in the next ten years from holding the copyright. I think the multiplier should be a little higher, or potentially you should get the right of first refusal -- if someone says "I want to steal it from you for $1,100" you can then name your price instead, and as long as you are willing to pay 10% of that price you basically get to override the attempt.

Also note that the initial copyright grant is free in this proposal; so you get 10 years of monopoly on distribution.
