Is Yosemite really closed??

I was camping in Yosemite. Had a reservation to Oct 8. Was told to vacate by 3 pm on Oct 3. In my opinion the way the closure was handled was mean spirited, petty and done to cause maximum inconvenince. On Oct 1 the Park Service put sandwich board signs saying "no parking" and cones in all the turn outs and parking areas people use to look at the sights. I guess you were suposed to use blinders and not look at the cliffs or waterfalls. My neighoring camper went to go fishing on Oct 2 and was stopped by a Ranger saying the river was closed. I was riding my bike on a bike trail and was told by a ranger all the bike trails were closed and I had to get off and walk the bike back to my campsight. I told him no way was I walking 4 miles back to the campground and rode off down the highway. He didn't say anything or try to stop me. The volunteer work campers were told to stop all activites and not answer any questions. I guess the government has forgotten the parks belong to the people.
