Yes, you can do that. But when people show up to your arena and want to walk inside, you should let them try to pay to do so.
Let me explain this another way:
In both the 2005-2006 and 2011-2012 seasons, scalping was allow on the Coliseum property. In 2005-2006 Wake averaged 14,655 attendees and in 2011-2012 Wake average 8,675 attendees. The loss of the 6,000 attendees per game was not due to the scalping policy, it was due to the product on the court. Wake has not even received votes in the AP top 25 poll since 2009 - not once did a [name redacted] team even receive a single vote. Let that sink in.
Attendance is up this year compared to 2010-2011 (when scalping was allowed). Plus, if scalping is really so important to you, you can buy tickets on the sidewalk as you walk to the stadium.
