Why not proof of stake?
PoS is drastically cheaper to do a 51% attack than PoW as the attack only costs the 51% cost of carry and insignificant transaction fees to enter and leave the position compared to having to organize the purchase of and rental fee for 51% of the hash rate for the target block time.
I've seen crypto be used largely for flash money grabs and little else since the entire thing started and I'm largely convinced that until volatility, speed and energy consumption are fixed it will only remain in that realm until it's inevitably cracked down on by various governments.
Those are some pretty big issues to solve and personally I think ETH is poised with PoS to solve those issues, or so I've been led to believe, and offer utility in those every day transactions but I'm not holding my breath because of issues like that that you've pointed out and people who only view it to be used for that aforementioned money grabs.
When I've used crypto I've used ETH exclusively for my beliefs there, but I'm really not all that convinced this will ever be more than a novelty in current form.
I'm no expert in the field and I don't even generally follow crypto more than the passing news article, but this continues to be my general perception, especially when things like Doge are surging in value with really no discernable economic basis.
Let the crypto hoards now rain down upon me.
