To add to the conversation, Gold is himself a realm jumper, at least by the time we get to pre-curse EF with Regina.

Back when he had his initial conversation with Blue, this was right after Rumple had become the DO (Bealfire was 13 when Rumple took the powers, and Bae was no more than 15 when he went through the portal, and my headcanon puts him at 14). he had barely started learning the capabilities of his powers (which are probably far greater than anything he could imagine at the time). in the century or 2 that passed since that time, Rumple investigated many ways to traveling realms in order to get to the LWM. In the process, he (headcanon here) likely learned ways of transporting himself between magical realms (not what he wanted, though useful), but either did not bother to learn how to send others, or just chooses not to do so. Which is why he is seen in the LWC talking with Victor, and in VE talking with Jekyll and Hyde. But he had Jefferson act as an escort for Victor when Victor visited the EF to obtain his heart, not wanting to be bothered with the details of transporting someone else.

They don't show it because it serves no purpose to any of the stories told, but I imagine that if Gold needs anything from the EF, he can just go there and get it. It's probably part of the reason his shop has so many magical items (though there is an untold story there as well, since that is clearly not the only reason).
