Probably true. Doesn't mean we need Drivechains though. We are also getting ahead of ourselves somewhat with arguments about security budget, blocksize limitations tail emissions, limitations of LN etc. It's working fine today, will work fine to onboard a few more hundred million, and yes, will likely bit scaling issues in the future, which means we have time to discuss, scope, test and get consensus on ways we might address that at or just before the time it becomes an actual real world problem.
