There are stable coins that are closer to currencies.

I note that the US dollar is declining in purchasing power every year for decades.

Crypto has increased its purchasing power.

Yes, but those stable coins are only stable because they're based on, or directly tied to, the dollar or other national currencies. If they (stable coin) replaced the actual currency for usage everywhere, they wouldn't be stable any more because the only thing that stabilizes them, the currency, would be gone.

Yes, the dollar has declined in purchasing power for a long time, but that is mostly just natural inflation of a currency. And it's based on government policies and interest rates and so on. Actual stuff causes those values to rise and fall. Crypto currencies fluctuate wildly because there's nothing that their value is based on, except the fact that it's crypto and has value because hell, why not? Crypto's purchasing power (where accepted) has increased greatly in a short time frame. But based on what? There is nothing actually increasing the value of the crypto, aside from the crypto itself. Nothing else has actually increased in value that would cause the crypto to do so. You say it's an asset - sure, though I'd say it's merely a paper asset, but it's not even that. It's basically a valueless store of value.

The purchasing power of the US dollar is inflated away purposefully as a matter of economic policy.

Every year, it buys less.

In fact, since 1900. The US dollar has lost 95% of it’s purchasing power.
