When I was about 16 I had the same mindset of a fully grown Sierra Fellers
I remember there was about 100 skaters skating this six stair by the beach. Whenever someone needed to use the stairs the skaters would get pissed (myself included) until i heard another skater say "How dare they use these stairs for their intended purpose" and it has forever stuck with me.
The coolest part of street skating is the street element - watching traffic, bust factors, pedestrians, cracks, etc. If you don't wanna deal with these things, go back to the skatepark.
