Sockets aren't point to point, but non-broadcast IP addresses are.    
So you're half right... :')

Some socket APIs let you broadcast with an IP source address of  
0.0.0.0 when your network interface has no valid IP address  
configured; in that case, you can use the socket API.   Others do  
not; in that case you need to use something else - e.g., BPF or LPF  
or DLPI or something even more hacky.   It's an unfortunate omission  
in the unix standardization effort, IMHO.
