There is a clear reason for that.
Markets are formed by rules. Without rules there is no market, just a bunch of traders.
A market is a place, where people meet to exchange work, goods and values. Like a classical flee market or local farmers market.
This place is owned by someone. The owners are often not the ones, who manage the market.
The market manager establishes the rules (Which can't be against the will of the owner.)
And the merchants will not be encouraged or very active, if the rules are shitty for them.
The markets of our national economies are owned by the sovereign, us.
But the rules are made by the legislation.
Before rules, there were only two people, meeting and exchanging things, they agree on.
But on a market, you are forced to use the units of a certain payment system (money), use calibrated weights, need to put price tags on goods and so on.
You are not allowed to put cheap stones on the bottom and only some apples on top.
Without rules, ancient and especially modern markets collapse quickly.
The same applies to European single market. The place is just much bigger than a traditional flee market.
You want to sell something here? Stick to the rules!
Have you ever seen a market manager of a flee market? Walking around proudly like a boss.
Don't try to put your booth there without asking and paying the fee.
You will be kicked out of the market in no time.
And they won't be friendly.
