EOS takes a unique approach to creating a highly scalable platform for smart contracts. EOS prioritizes scalability and end-user experience rather than maximal censorship resistance.
Either these platforms will offer strong assurances ('permissionless-ness'), in which case they will attract 'sovereign-grade' attackers (and 'platform-grade' censorship resistance will be insufficient) OR they will embrace censorship and permission-ing, in which case they will end up as less efficient varieties of today's centralized platforms. Regardless, neither path appears sustainable.
Your elaborations seem to consider as if EOS was to become the only dAPP platform around, I think everything will be smoothed down by the fact that there's many other cryptos and platforms, I don't think we'll get to the point of EOS monopoly on dAPPs
