I eat (and enjoy) meat myself, but if there's a way to get that texture and flavor (texture is the most important part, I think) in a healthier and more sustainable way - I'd love to see it happen so long as the final result is actually more efficient to produce and healthier to eat. As you say, many artificial foods have ended up being worse than what they were meant to replace.
As others are pointing out, this is a poor argument and should not be modded up.
Build a dedicated line, from everybodies house to their work
That's a strawman argument. I simply suggested if we could commit to the cost, extending public transit options further into the suburbs is a nice thing to have. Whether this means more buses, or extending a metrorail further out like they have (successfully) in Virginia. It could also mean having more options between cities.
You understand the underlying economics?
No need to condescend. Other countries manage to have more frequent, reliable, and accessible public transit options (rail and bus) than we do, and they seem to make it work. I'm sure our brightest minds could figure out a way to do it. At the very least it is worth a try.
