I hope someone talked with lawyers that know what can be done.

I would love a (more) unified system (tax, rules, etc.). Multiple organizations/think-tanks recommended more unified systems for the EU on this topics.

The problem is if it does not fall under the EU competences it will be hard to implement at that level. To quote:

> While the businesses and objectives targeted by the 28th regime are specified to some extent, it is unclear which firms would specifically have access to it, and which aspects of the business code would be covered. The competences of the EU are likely to constitute boundaries in this respect.

In a way, it's like programming. The difficult part are the exceptions, corner cases or unplanned interactions. Countries are very reluctant to give up control over some topics (tax being one of them) and they also have lawyers.

I welcome any help entrepreneurs can receive. But after trying it a couple of times (software stuff, might be a specific case) I personally didn't find the rules for creation/tax were that of a problem, compared to the requirements that in many other instances I felt were imposed to the newly/newlish formed enterprise (ex: want to apply to a project? you have to have existed for 3 years; want that subsidy? you need to show us you are having X partners) to lower the risk for the existing (public and private) organizations.
