Making the case for changing streets to either not carry cars or enforce extremely low speeds is also difficult. We need fast, convenient transport so we can spend more time on other things, after all. But I also don't think reality is always walking 10 blocks to get to the park. That may be true in some implementations, but it doesn't have to be that way and it was not for me growing up. And even if it was, kids used to bike much longer distances on the sidewalk to get to their friends' places or a park or whatever.
