It's amusing that you're trying the crypto volatility angle, as Bitcoin drops over 10% today. And Bitcoin does nothing but "store value", while Arweave has useful market purpose.
Even if Arweave suffers heavy volatility, they collect for 100 years upfront at today's prices. Considering storage prices are dropping, there would have to be massive downside volatility to not have at least 10+ years...
which is wayyyyy more than most blogs/websites need. A blog can update every day or week. So you've really failed to address the main issue of decentralized storage/CDN to avoid Cloudflare.
