What you're seeing in the Scotch boom isn't the sudden uplift of a formerly humble drink; it's the discovery and rediscovery of a noble drink by new markets. When and where rum has seen boutique, high-end mini-markets, they are usually driven by the marketing efforts of a firm or two, and they are usually impermanent. Even these usually promote rum as a mixing component -- which is a good way to remind people to consider rum as a vital component of the liquor cabinet, but not a great way to get them to appreciate it.
Now it's all a matter of taste but when it comes down to it, would you rather have a cheaper good quality rum or an average/poor scotch for the same price?
Scotch distillers are increasingly putting out non age statement bottlings of younger Scotch for prices that they once charged for 10 or 12 year matured Scotch, I think if they continue to do that those who've developed a taste for good spirit will look elsewhere and find Rum which is a very handy replacement.
The global rum market is dominated by a handful of huge beverage companies, all of whom have historically marketed their rum as a mixer. The two forces working to counter this image are the small-batch importers and the internet rum-aficionado community. In time, they may prove successful.
I will say this much, at least: there has never been a wider selection of great rum so readily available in the United States in my lifetime. Anyone whose opinion of rum has been colored by the paint thinner that Bacardi puts out should consider a bottle of Diplomatico, or aged Flor de Cana. The prices and quality go up from there, but for my money, those are some very good and very approachable sipping rums.
But you're right that there is a whole, wide world of high quality drinks to explore. High-end rum, tequila, even gin have a lot to offer in terms of slow, thoughtful consumption. [0] http://www.templetonrye.com/home/
You should avoid Templeton just because of the douchebag factor.
TR is a bit disingenuous, but not evil. It's a decent tasting product run by a small company in the middle of nowhere; certainly it was damn near impossible to get rye a few years ago and TR's marketing helped to change that. But like most whiskies, take the marketing with a demijohn of salt.
+1 to Willett.
Regarding Templeton, here's a decent reported source:

I read several years ago that Templeton bought its rye from a distillery in Indiana and it wasn't much of a secret that it wasn't distilled in Iowa. So, maybe not the MGP name was known, but the name is kind of meaningless.
Further, they are walking a very tight line with regard to what additives they are using. In some places they are adamant that they are following "traditional" processes, and in others they happily invoke the additive to side step allegations of fraud/false advertising.
Personally, I have no problem with NDP brands, and think that the mixing of the various ingredients goes a long way to determining the quality of the final product. So even coming from a distillery in Indiana is not a problem (or even having a compelling Col. Sanders character sell your sauce).
But Templeton really does take it to another level. Not sure if that level is "evil" or not. But certainly douchbaggy.
Obviously a scotch drinker is going to want to stick to scotch, but there are very fine examples of other distilled beverages (rum, cognac/armanac, bourbon, anejo tequila/mescal) that are going to be as complicated on the palate for fractions of the price. At some point people will switch. The reason I haven't, honestly, is that there are still "bargains" in middle market scotch... it's not clear that intrinsic quality is driving market, as opposed to scarcity or marketing.
EDIT: sorry, got back to this thread a bit late. I echo the other commenter on the Ron Zacapa 23 or Centennario. That was specifically what I had in mind, and is a great launching point for exploring them. https://www.masterofmalt.com/samples/ will let you get 30ml samples for a modest markup and is a great way to try a lot w/o ruining your finances or liver. Astonishingly high end single malts available that way, too (I have no incentive to promote them whatsoever)
As for cognac, bourbon and tequila, I can definitely see your point there.
