well, you can't just turn on hospital capacity like a faucet. No-one knew/knows how long or severe this is going to to run. Omicron might wash over the population causing little harm and leaving everyone resistant, or the 'RHO' version could show up tomorrow with double the mortality of delta. Facing that kind of uncertainty throwing billions into hospital construction as opposed to other public health efforts (vaccines etc) isn't so simple a question. Building out hospital space to modern code and practice requirements is phenomenally expensive - esp if done in a hurry, and if that capacity ended up empty in 24mo the people that spent the money would be fish in a barrel for the political 2nd guessers. It may come to it, I just don't think it's an easy or trivial decision to make.
