Tampa's STH terms and conditions

You can read the whole thing here I just found the resale clause the most interesting:

<<5. Resale Limitations: The Tampa Bay Lightning acknowledge that STM may not be able to use each of the tickets in their STM Account. STM acknowledges that the spirit of being a part of the STM ‘club’ is not to generate financial gain or benefits for STM, but rather is rooted in a desire to support the Tampa Bay Lightning. As such, STM acknowledges that his/her resale and/or trade activity may be monitored and tracked by the Tampa Bay Lightning, and, in the event that STM sells, attempts to sell, or engages a third party to sell on his/her behalf a majority of the Account tickets, the Tampa Bay Lightning reserve the right to cancel the STM Account>>

What is everyone's thoughts on this? Is this over reaching by the team? They're your tickets, you bought them at an agreed upon price. If the opportunity arises to sell them for more, why shouldn't you be allowed?
