This has been discussed ad nauseum. First, the covid title expired. Nothing to be done about that. Second, resources are short. The bill, killed by Trump, would have shortened the time for asylum processing to 6 weeks, would have been a huge step forward. Third, some of the steps you speak of had been successfully challenged in court. It's why Trump himself when President said he needed legislation to address these very issues.
Face facts. The reason the border has not been fixed is because both sides like to have the issue to run on. And that is exactly why the GOP has killed it this time.
Again.
