Using same logic you can say that "Sprint gives you unfair advantage because it let you move faster than players who don't use it". Ridiculous.
Clicking faster means better skill.
Yeah, it is a huge problem of CubeCraft (especially macros). However it is very controversial point for drag ban that сouse debate for years. Personally I don't like the way moderation team reviewing click-related reports, so it is strong point for drag click ban in my opinion. But it can be solved by changes in moderation team (that may result false bans). So it is really controversial point and I think that so unpopular decision is not one Cube should make.
Player with Keyboard and mouse that normal click and player with keyboard and mouse that drag click against touch player would be on pretty same level of disbalance.

(problem of advantage of KbM under touch player is still a lot more serious than drag players having more CPS, as I said above "Player with Keyboard and mouse that normal click and player with keyboard and mouse that drag click against touch player would be on pretty same level of disbalance.")

(Nether armor and sword of guy who mixed up their base with mid can be a strong argument against drag clicker with leather armor and wooden pick who killed all map before they was able to notice it)
Everyone can beat 300 CPS player if somebody can't set adequate CPS amount in autoclicker than they diffidently can't aim.
Are you serious or visited same party as
@CeruleanPrism81 last night? Allowing modification that would provide unfair advantage is ridiculous. Problems in moderation is not the reason to remove rules.
Cube better to ban something controversial than allow something unfair. Btw use of illegal modifications (cheats) is disallowed under
XBOX COMMUNITY STANDARDS.

(CubeCraft is not a completion, it is a place where you can spend free time for fun. So 100% equal conditions is not a thing here)
It's better to ban drag, than allow macro. Macro is an actual hack.
It is solution Cube deffintly should try.
Macro is realy huge issue and the reason player wanting drag click ban more and more.
