Yes and no, clean streets have a lot to do with a government that gives a shit about clean streets.

If the government cares about clean streets AND provides trash cans AND empties them AND has laws and punishment for littering AND actually assigns police to watch and catch people who litter, that's how you get clean streets.

Maybe we can do without the draconian punishment, but as a citizen from a country with trash and filth in the environment I live in, I don't really care about that detail and wouldn't mind a little over-correction.

And I would really like to see the people who litter suffer for doing it. As a bonus.

But ultimately I just want clean streets. If there is a strong opposition to draconian punishment for littering, I can compromise.
