There's no way you've spent more than a week total in the city if these are the conclusions you've come to. Barcelona, like all large cities, has its drawbacks, but they're not the ones you've listed.
1. Climate is far better than most large US cities, and moderate. July highs of 86F are hardly "extremely hot".
2. Absolutely not true for 95% fo the city. Maybe get out of Gotic next time?
3. I don't even know how to respond to this point. Most cities have dense centers. Few have buildings like the Palau de la Música Catalana, the Sagrada Familia, or the Cathedral.
4. High cost of life? Compared to the rest of Spain, sure. Compared to the US? Not particularly. Salaries are low locally but purchasing power is higher.
5. Again, no idea what you're talking about. Most people walk or take the metro everywhere. Average air pollution in Barcelona is lower than most major US cities and many other major European cities as well.

How about August. I was there in September, it was 28-30C throughout the day almost every day. Either way, that's a personal preference.

I did and I have also been to places outside of Barcelona. For example, I've had much better quality food at same or lower prices in London, Rome and Milan. The truth is, in this regard, Barcelona is very much second rate.

Sure, I don't really mind it. I was somewhat amused at how certain parts are overbuilt, but not with really old buildings, but just stuff that looks to be from the 70s or 80s. Most historical cities have done a better job at protecting their historical city centres.

I think your claim here is obviously false. According to Numbeo:
Local Purchasing Power in Barcelona is 40.50% lower than in San Francisco, CA
Local Purchasing Power in Barcelona is 20.21% lower than in New York, NY
Local Purchasing Power in Barcelona is 48.42% lower than in Austin, TX
and so on. I don't think there is even one mid-sized or major city where that holds true.
