You still get the benefits of increased property values due to strangling supply in the face of demand. Only with prop 13 you stand to net even more money, and if your dad gave you the house he bought in '70 you are taxed like you have a little shitty 20k house in boise.
Most variations of NIMBY-ism arise from a desire to preserve the status quo. That's exactly the kind of rationale that went into enacting Prop 13. The more valuable the status quo is, the more people will fight to maintain it.
Even if there is a bright future ahead, people will limit change. This is in large part because the benefits and costs of change are not uniformly distributed, and when people have a valuable status quo, change represents significant risk.
The attitudes may be in the same direction, but they are far less extreme and taken far less seriously by others. People complain but at the end of the day buildings actually get built in Seattle.
I live in Seattle, where the attitudes of residents and attitude to building are similar, but we have no Prop 13. How is it possible?
