Scrapping Scram

I was reading that NASA will be scrapping its Scramjet research
program after the next X43 test:

Is scram considered to be the weakest of the available technologies to
get into orbit?

I'd thought that this particular technology was supposed to be the
most promising for usage by the commercial mainstream for rapid
intercontinental transit, as well as high-speed intercontinental
bombers and cruise missiles.

Maybe NASA should sell its technology to Richard Branson, if nobody
else will pursue it. It seems a shame to waste it. Or will the
military take up the mantle?
