>> It is nearly impossible to fully comply, and may actually be entirely impossible, based upon how much conflict there is between the 28 different interpretations that this will be subject to.
By "28 different interpretations I assume you mean those of different member states. It would actually be 27 now that the UK is leaving, but even so, the GDPR is a regulation (General Data Protection Regulation) and not a directive, partly in order to eliminate inconsistencies in national laws. To clarify, as a regulation, the GDPR does not need to be passed into national law.
Additionally, this reduces the burden on companies that would previously have to deal with multiple local authorities, in the context of the Data Protection Directive.
Further, there are provisions for the consistent application of the GDPR across all member states, particularly a European Data Protection Board.
This is from an article I quoted earlier:
Coordination and Consistency
Under the Directive, there has been a certain level of coordination in interpretation and enforcement. Apart from informal contacts among authorities, there has been a succession of non-binding opinions issued by the “Article 29 Data Protection Working Party,” an advisory committee comprised of representatives of the national supervisory authorities (commonly termed “data protection authorities” or DPAs), along with the European Data Protection Supervisor appointed by the European Commission. Under the Regulation, that group will become a more independent and powerful regulatory body called the European Data Protection Board, tasked with ensuring “the consistent application” of the GDPR. An entire chapter of the Regulation (Articles 55-63) is devoted to cooperation and consistency, with procedures for multiple DPAs to coordinate investigations and promulgate consistent decisions and policies reviewed by the Board and reported to the European Commission.
One feature of coordination that should be helpful for multinationals is a provision for companies to work with a “lead supervisory authority” in the country where the company has its “central administration.” That authority will then coordinate with the authorities in other countries where the company operates, attempting to achieve consensus on issues that affect all of them.

Generally, I have no idea why you say that the GDPR will be nearly impossible or actually impossible to comply with. Different member states have different regulations for drug use, for instance, but that is never used as an excuse to violate drug laws "becuase they are impossible to comply with" due to different national interpretations.
