We do not need priests to have faith in God or pray.
Catholics (the church that Jesus left us, with Peter the first man in charge) needs priests to consecrate the hosts. We need priests to reenact The Last Supper, where Christ left us his Body and Blood.
Anybody can shake salt on a wafer, or just forget all about the Last Supper or ignore what the Lord said about it, but Catholics need priests.
You may not need them, but I need the Truth. Catholics need the truth.
