I'll explain it so a child can understand it.
On your way in the gate you pay for the roller coasters, attractions, security, cleaning services, maintenance, trains, roads, water rides, etc. Just like in America.
If you climb over the fence without paying, you get thrown out and banned for life. That seems fair to me.
Being inside Disneyland, and all paid up with a ticket stub in pocket, doesn't stop you from being able to pay a kid a quarter to hold your cotton candy while you go to the public toilet which is similar to government toilets all across America.
Other than nuclear warheads, there is little difference between America and Disneyland as they are both run by goofy cartoon characters.
