I don’t own a business, and assume you understood what I actually wrote.
But let’s say I did own a business. In that case, you’re right to point out that providing a restroom unilaterally would make each business owner worse off. That’s why it would require a tax incentive, not just asking nicely.
The homeless are going to poop somewhere. They don’t have money for pay toilets. Wherever they go will require cleanup, and it’s better for everyone if that’s a restroom than if it’s the sidewalk.
The people doing the abusing here are not the homeless.
I had a very successful experience! My grandmother had no idea how computers worked at all, so I set up a very stripped-down Ubuntu that didn’t even allow multiple windows open. I could easily remote in whenever she had an issue.
She used it to check her email, read the news, and watch Obama’s weekly address until the week she died. (Unrelated to the computer)
