Alrighty then.
First of all, you keep using legality to argue safety, as if they're the same thing. They're not. If you want to say that pedestrians are generally unsafe then fine, no argument. But see my point #3.
Second, cycling and walking advocates complain that the onus seems to be all on them. Like yours, their perspective is skewed by bias. The public education campaigns are actually very much split amongst all road users.

Third, it doesn't matter who's responsible. If I can do something to help reduce hazards others create for themselves, do you think I shouldn't do it? We need to look at aerospace safety as a model here. Even if most crashes are due to pilot error, that doesn't stop them from improving technical standards and training in all areas of the aerospace industry as a result of those crashes. Road safety isn't a competition about who's safest. The goal is to save lives, bottom line.
Fourth. If you still insist that only those responsible for creating hazards should do anything about it, the data shows a 50/50 split in responsibility for deadly collisions between drivers and pedestrians.

Fifth, how on earth is it defensible to argue that you should be able to get to work a few minutes faster at the expense of people's lives?!?
EDIT:
Sixth, your whole reply was just a deflection around my point that Hack was basically right about the inappropriateness of the lowered limits in rural areas.
