Naah, I think I would rather use the 32 ETH to trade even on spot market. I can make far much more than I can earn in staking rewards 
You'll earn a lot more by trading ETH than staking it. This is the same with other cryptocurrencies on the market. But not everyone knows how to trade, so staking would be the preferred choice for the average person like myself. Believe me, 32 ETH is a hefty sum of money if we consider today's market price. There are staking pools for people with less than 32 ETH, but I wouldn't count on them since it involves a middleman in the process. Staking ETH yourself, would be the most decentralized and secure path to take. We'll have to see if ETH developers decrease the staking requirement or leave it as is. What matters is decentralization. As long as ETH can remain decentralized with PoS, there should be nothing to worry about. Just my thoughts
