Storing of Bitcoins is against Bitcoin.
No one will offer services for Bitcoin.
Spend Your Bitcoins.
You could always do both. Put some round amount in cold wallet and actively use the rest. Biggest problem is not many people have any sort Bitcoin earnings, that's currently the biggest obstacle in BTC adoption and it's use as currency.
Sotring bitcoins is not against the bitcoin rules everyone has the oppertunity to do with his bitcoins whatever he wants to do you know and that is nice because i dont like to use bitcoins everywhere so i can hold some of them you know.
I agree with you, its not really against on bitcoin because as you mentioned too no one could able to force us on what we should do on our bitcoins. Its our decision if we hold or actively spend them because we have different perspective and expectations into bitcoin. If we actively spending our bitcoin it could really help the bitcoin ecosystem to grow.
