I'm not sure wtf this has to do with the homelessness issue but if you want to start a completely separate discussion about it:

• Yes absolutely those should be brought up to some sort of code and all the ones I've seen lately (I live near a lot) have been reinforced to be safe, heated structures protected behind concrete barricades
• Many people are in favor of moving away from the uniquely American concept of letting car use take over such significant portions of our cities. Letting restaurants expand patios brings us in line with the rest of the developed world.
• There's real economic benefit to it (increased restaurant capacity, pandemic safe seating for local businesses) and the amount of parking spaces they take away is negligible
• I could keep going but its not really worth it, since your red herring of a comment barely deserved this much effort and you've probably stopped reading anyways.
