I wouldn't compare Plugge to Pérez at all. It's not about being able to buy Mbappé, it's about a more sustainable model so you don't have to beg people for money the whole time. That if 1 person decides he doesn't want to go through with sponsoring that you have to lay awake at night for 6 months finding someone new or else the team will disband and all riders and staff will lose their job.
This will probably still be the case, since the teams will keep forcing each other to raise their budgets if they want to stay at their current levels within the sport. Mo money, mo problems.
