After reading about the issue of address reuse I think it wouldn't be that bad if accounts were used more (with different addresses). If you mean the same type of accounts here.
Account is a reusable address with its downsides.
Yeah that's what I thought, so you'd need to have to generate new accounts frequently to prevent address reuse. Maybe an approach for PoS v5 that's more "under the hood" and doesn't bother users too much (because users will do mistakes) is the better way
