Regarding starting a business, Estonia has made it really easy with its e-residency: https://www.e-resident.gov.ee/
(This happens particularly _visibly_ due to the EU's weird structure. In most democratic states, there are consequences for the executive trying to do things that the parliament is definitely not going to allow them to do (in some parliamentary systems failure by the executive to get something through tends to result in the executive becoming an ex-executive), so if the executive has something it doesn't think it can get through, it keeps quiet about it; it may talk about it in private but is unlikely to risk a defeat by parliament. In the EU system, there are no consequences, so you do tend to see the EC pushing things that have little realistic chance of getting through the parliament quite often.)
The opportunity is there not only for the EU, but pretty much anyone who demonstrates good will/intent. I hope we end up with a consensus on something that won't be abusable by individual countries
However, while the EU appears to be the good guy in this case, it is also notoriously anti-encryption (as is the UK), and these economies are also notoriously difficult/bureaucratic to start businesses in, so my hopes are not high for Europe's resurgence as a global technology leader. Without changes, I think Europe's best ambition will be self-reliance rather than projecting global soft power through owning the means of internet publishing
