You’re comparing two completely different positions. Most sacks are made from positions that get relatively few tackles, and most tackles are made by positions that make relatively few sacks. That’s the nature of the beast; rushing the quarterback takes you out of position in run support.
Generally speaking, DEs (in base 4-3 systems) and OLBs (in base 3-4) make sacks while MLBs make the tackles. Emphasizing sacks while devaluing tackles will make both positions effectively worthless, since the steady tacklers will be undervalued while the sackers will be so inconsistent that their contribution can be mostly ignored like kickers.
There are only so many roidheads who get to play the Raiders twice a year to go around.
Check out ESPN’s leaderboard for last year. Compare the rushing and receiving leaders with the tackle and sack leaders in the context of fantasy points. Note that touchdowns are not included. To make the IDP guys equivalent to the skill positions, sacks would have to be worth 10 and tackles worth 1. If you didn’t want the IDP guys to be equally valuable, maybe halve those numbers to 5 and .5.

Note that exactly one guy made both lists.
For a sacker, 7 tackles wouldn’t be a “fairly routine” day; it would be a double-plus super good day. Given all this, let’s say you made sacks worth 10 and tackles only worth .5 to devalue the compilers and favor the studs. I might still go with a tackler simply because their points are more reliable. The best sacker in the league averaged 1.1 sacks per game, meaning that every single multi-sack game was accompanied by a completely sackless game. Thus, there are days when he would score basically nothing.
I’ll take a few guaranteed points every week versus points one week and none the next. Most fantasy players would; that’s why running backs are the most valued players.
