I meant, it's optional to use the drivechain.

But yah, it's all for one and one for all, adding them.

No, it's not really optional. It exploits one of the vulnerabilities in the Bitcoin protocol: the fact you can soft-fork in additional chains with just a majority of mining hashing power. It would be good if we found a way to fix this.

In the future, are transaction fees high enough to keep the security high enough to offset the drop in blockchain subsidy? If prices drop temporarily due a global virus or wide-spread large-scale fraud or government ban, would miners shut off their rigs until the price recovers?  Would the price climb, while mining was down?
