Inflation can be very costly, especially for the most disadvantaged who do not have investments to hedge against the rise in prices. It may have a positive first order effect in the short run, but it is an elusive one.
Inflation, if out of control, has the potential to bring the interest rate to levels that would turn borrowing extremely costly --therefore making acquisition of capital more expensive, affecting productivity.
Another side effect is that the government debt could become extremely burdensome, which would force the government to essentially print money to pay its debts. That is effectively a tax (called _seignorage_) on the population. In order to pay its debts, the government prints money, which in turn makes goods and services more expensive --i.e. _seignorage_. High inflation can affect consumer behavior and depress economic activity, which would lead to unemployment, it happened many times, and it is called stagflation. A slower economic activity coupled with increase in prices could then make production more costly, which would push inflation even higher but also increase unemployment.
The key here is whether inflation would get out of control. The Fed seems to banking on the idea that this high inflation is transitory, which means that despite its current high levels, there will be some accommodation in the medium run and things would go back to a stable and acceptable target level. Some, like the article above, does not think so. If that's the case, then the Fed will need to act soon.
