Technology is 1/3 of what you need to replicate. The other 2/3s are developers, community and gradual distribution of coins over long enough time to draw all this community together.
Bitcoin technology was replicated many times in copycat clones, it didn't help them because there were not enough people and talent behind them. For one or other reasons people and talent have gathered behind Monero. Go ahead, take source code of Monero and try to replicate if you can. You will fail like Bitcoin copycat clones failed. Technology by itself is nothing.
