Accepting Bitcoin as legal tender wouldn't harm for the economy even it's on bear market, this because people are use it as a currency and not mainly for store a value. Actually countries that doesn't accept Bitcoin as legal tender would harm the economy since they're not use Bitcoin regularly due to it's not accepted on merchants. But we're talking if there's many people who hold Bitcoin, if it's only small group, then the effect is small.
The best option is don't force the countries to accept Bitcoin as legal tender, but governments shouldn't ban Bitcoin and allow any merchants if they want to accept Bitcoin payment.
I, agree with your opinion, there are indeed many countries that do not accept bitcoin as a legal tender, and indeed certainly cannot be forced, but it would be nice if the government did not prohibit the buying and selling of bitcoin and crypto, but mostly even though bitcoin is not made legal tender, but the government mostly allows buying and selling of bitcoin and crypto, because with the sale and purchase of bitcoin and crypto in the community,
Many people's economy is helped because they can buy and sell bitcoin and crypto.
