The post I was replying to said "Or just regulate the dumb behavior of these dumb start ups to not distort the market in dumb damaging ways,"
I assume that the proposed regulation here was larger in scope than the Portland City Council rule, especially since that rule does not do anything to correct the market distortion -- arguably, it makes it worse, by mandating that they undercut economically viable approaches, rather than just letting them do so. That was what I was addressing.
This particular rule is innocent enough on the face of it -- it has only two requirements [1]; that they cannot charge more than 10% of the purchase price, and that they cannot reduce payments based on compliance with the first part. To enforce this (especially given how broad the definition of a delivery service is) will be a supreme act of discretion, and clarifying this rule and eventually handing it off to the local commissioners of the counties' health departments for enforcement will complete the slide into the endless land of bureaucracy.
