BE24 pilot reported the nose gear collapsed on landing; and the runway was blocked until the aircraft could be moved.

Narrative

On landing the aircraft porpoised and believing I could settle it out I failed to apply power and go around. On about the third bounce; the nose gear collapsed and because other aircraft were in the pattern I attempted to steer the aircraft off the runway to the left side. The aircraft came to a stop with one main gear on the runway and as I shut down the aircraft; I warned other planes in the pattern that I had a collapsed gear. There were no injuries or damage to anything other than the nose of the aircraft. Within about 30 to 45 minutes; help arrived and the aircraft was removed from the runway and delivered to its hangar.[Some factors were] the pattern was a bit busy and I was trying to get on the ground and off the runway efficiently in consideration of other planes in the pattern; complacency on my part thinking the a/c was not in danger of damage and that I did not need to waive off the landing.[I learned to] be more focused and think ahead if a landing is not going well. Be more proactive in going around. Take more care to avoid situations where I think I'm helping others by getting down quickly and off the runway in a hurry.
