If there is any movement in the system and you use a solid pipe  then the pipe could fracture leading to brake failure.

You need a flexible hose to allow caliper movement.

Seriously dangerous without the flexible pipe

Copper pipe  :o. You are freaking me out.
Brake lines must be steel. Some steel lines have a copper wash to protect them. Is that what you have ?

What is wrong with copperpipes?

Offcourse you need hoses to connect them to calipers.

The copper ones are usually a copper nickel mix. Steel rusts which is why most replacement brake pipe is copper based.

Yeah, well I do live down under & here the law says no copper pipe.
Apparently it has no where near the pressure rating as steel & will not pass a roadworthy inspection for registration.
The steel pipes here are zinc coated & I have seen copper plated ones as well.
A crack or a rub on the rubber or  braided hose puts you out of roadworthy as well.
A power assisted brake hydraulic system can attain 1500 psi.
Lets be safe eh ?

The copper ones must be legal over here as I've had several cars with them fitted that have passed the UK mot test.

Those copper/nickel ones you mentioned are very likely good.
 But I would not use soft pure copper.

When I was in Canberra I put a booster on a non boosted car, the local brake specialist made up the lines for me out of copper.
